1 Brief History / Hanes Cryno Camlas Abertawe

Constructed 1794-1798 by the Swansea Canal Navigation Company, the canal rose 375 feet through 36 locks from sea level at Swansea up the valley to Abercraf. Built to carry coal down to industries in the Lower Swansea Valley and for export, this new link to the sea enabled development all along the valley of industries and the towns we know today.

Canal boats were built at yards along the route, the last being the “Grace Darling” in 1918 at Godre’r Graig.

With the construction of the Swansea Vale Railway, revenues on the canal declined and 1931 saw its last commercial cargo trip, though horse drawn boats were still used for maintenance and social events until 1958.

Wedi'i hadeiladu rhwng 1794-1798 gan Gwmni Mordwyo Camlas Abertawe, cododd y gamlas i 375 troedfedd trwy 36 loc o lefel y môr yn Abertawe i fyny'r dyffryn i Abercraf.

Adeiladwyd i gludo glo i lawr i'r diwydiannau yn Nyffryn Abertawe Isaf ac ar gyfer allforio, roedd y cyswllt newydd hwn i'r môr yn galluogi datblygiadau ar hyd dyffryn diwydiannau a'r trefi rydyn yn adnabod heddiw.

Roedd cychod camlas yn cael eu hadeiladu mewn iardiau ar hyd y llwybr. Yr olaf i'w hadeiladu oedd y "Grace Darling" yng Ngodre'r Graig yn 1918.

Gyda chyflwyniad Rheilffordd Bro Abertawe, gostyngodd cyllid y camlesi ac yn 1931 gwelwyd y daith cargo fasnachol olaf, er y defnyddiwyd cychod â cheffylau yn dal i gael eu defnyddio ar gyfer cynnal a chadw a digwyddiadau cymdeithasol ar y gamlas hyd at 1958.



In 1948, Ian L. Wright, who will be 90 in July 2016, bought a two-seater canoe,'Cheswardine’ and set out to navigate all the South Wales waterways on behalf of the fledgling Inland Waterways Association. On April 19th, 1949, he began a two-day trip along the Swansea Canal.

The Inland Waterways Association, the brainchild of Tom Rolt and Robert Aickman, was just three years old. Its policy, as was made clear in its Memorandum to the Minister of Transport in March 1947, was to retain and restore all Britain’s canals. Ian Wright, brought up in Cardiff close to the crumbling Glamorganshire Canal, paid his one guinea subscription and became a member. He was then 21, a trained aerial photographer as a result of his war-time service in the Fleet Air Arm, and now a student at the Cardiff College of Art. His respect for Tom Rolt is obvious in the naming of his new canoe after the picturesque Cheshire village on the Shropshire Union canal, so lovingly recalled by Rolt in his 1944 book ‘Narrow Boat’.

As Wright and Penry, a fellow student and co-canoeist, set off to discover the condition of the derelict Swansea Canal, Wright started a record of the trip which he would send directly to the IWA Hon. Sec., the aforementioned Tom Rolt. It was a vital voyage. The Railway Executive, who owned the canal, were seeking official powers to abandon it. It was, like almost every other canal in the UK, in a bad way. The first half mile from Swansea Docks was dry and partly filled in, and then, from Maliphant Lock to Morriston, as Wright describes it, ‘the waterway passes through a barren waste of derelict copper works and slag tips, certainly one of the most depressing stretches of landscape one could encounter anywhere by canal’. Today, most of that stretch is a development and conservation site run by the City Council and Swansea University, and World heritage Status is a realistic aim. What little remains of the copper works are treasured Heritage structures with plans to rebuild one of the original bridges of the canal over a token one hundred yards of new water. How times change.

Back in 1949, Ian Wright and his ‘stout-hearted friend, Penry’ whose canoeing experience totalled just two afternoons, realised that paddling anything south of Morriston would be folly. It was, Wright says, ’dangerously full of submerged metal objects’. Coal dust blackened the water and made spotting the obstructions impossible. They decided to set off north from a disused approach at Morriston Station, 3 miles from the Swansea Docks, where the assembly of a canoe ‘would not attract unwelcome attention’. Wright was well aware that he would be on the canal without a permit and that he paid ‘no toll for passage’.

3. View of Morriston Bridge with the canal running to the right of the railway line, c1960.

Just before nine-thirty on the 19th April, the ‘Cheswardine’, a pre-war collapsible with a rubberized lining, was assembled and ‘carried as surreptitiously as possible over the canal bridge and into the water’. It was not 100% watertight. ‘I didn’t assemble it often, as it affected the leaks’, Wright comments. The two companions ‘proceeded cautiously’, assisted by a stiff following wind, the black water ‘turning occasionally a dull yellow’ which Wright notes, ‘detracted somewhat from the enjoyment of the place’. They passed brick kilns, engineering works and three lifting bridges, ‘none of which looked capable of being raised’.

Just as they were starting to settle into a good rhythm and enjoy the views, ‘Cheswardine’, true to form, sprang a leak. Their camping gear was getting wet and they were forced to stop at regular intervals to bale out. As Wright notes, with studied understatement, ‘this caused us considerable annoyance and delay’. After an enforced twenty-minute stop for wet sandwiches below Ynystawe House Bridge they reached the Cwm Clydach Lock, the first of 22 they were to encounter. They had paddled 2 miles from Morriston in 2 hours.

4. Cwm Clydach Lock, 1949.

This magnificent photo of Cwm Clydach lock, taken by Wright on the day, is fascinating not only to steam and canal enthusiasts but also because of the identities of the two young boys fishing. John Hutchings, the lad in long trousers, and his younger brother were born close to the canal and at sixteen John started work on the Swansea Canal, by then nationalised as the British Waterways Board. He worked his way up and was the Canal Manager for many years until his retirement in the 1990s. He still lives in Clydach.

A few minutes after passing the John Player Tinplate works, out of which the train (an Andrew Barclay Saddle Tank) is emerging in the same picture, the ‘Cheswardine’ reached the beautiful Clydach Aqueduct, the point at which today’s Swansea Canal emerges. Here the scene is much as Ian Wright would have seen it nearly seventy years ago (less the yellow and black water, of course).

The vast industrial complex of the Vale Inco Nickel Refining Works, one hundred yards further on, is still there too, though not now surrounded by ‘a half mile area devoid of vegetation due to the vitriol-laden atmosphere’. These days, it is a difficult job for the volunteers of the Swansea Canal Society to keep the rampant vegetation in check. Refining techniques have progressed greatly and the Clydach community receives regular community grants from this Brazilian-owned multi-national company.

At the next lock, Clydach Lock, Penry and Wright manhandled their 17’ boat, full of gear, across the main road, round the lock, up a steep bank and over the arm of the top gate. ‘It was’, Wright says, ‘a heavy boat to carry round all the disused locks in South Wales.’ Neither man had carried a canoe around locks with a full load of camping gear and provisions before. It was midday and they had been up since 4.00am when the ‘Cheswardine’ had started its journey by lorry from Cardiff. Now, after their assault course and back in the canoe, they came into ‘pleasant thinly wooded country’ looking down on the River Tawe close by. I am pleased to say that canoes once more frequent this idyllic section of the Swansea Canal, thanks to a generous grant from Natural Resources Wales.

8. Canoes on the canal, 2016.

Soon, however, the canal scene reverted to post-industrial decay. Wright and Penry were hemmed in by ‘a lengthy ridge of slag’ and the William Parsons’ steel and tin plate works (now the site of the Pontardawe Leisure Centre and the Cwmtawe Community School). Ahead though, they could see the elegant spire of St. Peters, Pontardawe’s parish church, a gift by Mr. Parsons to the people of Pontardawe, every stone of which had been transported along the canal between 1858 and 1862.

Here, at 2.00pm in Pontardawe, they rested, hauling ‘Cheswardine’ ashore at a building yard while they took refreshments. Below the Church they chanced upon the canal lengthsman next to his hut and raft. He bemoaned the condition of the latter, saying that the Railway would not provide him with the wood and materials to effect its repairs. In this way the Railways hastened the demise of their unwanted canals. Only one lengthsman’s hut, which was, to all intent and purposes, the mans’ living quarters, remains on the Swansea Canal today, lovingly restored thirty years ago by the founding members of the Swansea Canal Society.

This is it, situated by Ynysmeudwy Lower Lock where Wright and Penry arrived shortly after leaving Pontardawe. The Lower and Upper lock were, Wright says, ‘two of the most prettily situated ones we were to see on our voyage’. They still are, though, in need of much TLC. Here, the voyagers were helped by some local children who carried their paddle and gear while the two adults carted the canoe round the locks. It was 4.15pm.

The flow of the current downstream now became much faster and shallower. Penry got out and so too, eventually, did Wright, and the two men had to bow-haul ‘Cheswardine’ through five or six inches of water for the next half mile. The water level built up as they approached Lock 15, and what Wright describes as, ‘a veritable crescendo of locks’. The casual visitor would, today, be hard pushed to find the remains of any of these seven locks and the canal is but a trickle. The road builders of the 1970s were happy to use not only the line of the canal for the route of the A4063 but much of the lock stonework for its foundations.

The Swansea Canal Society is now applying for a grant to make this section a Heritage Trail. The remains of Thick’s Lock (lock 17) is the finest of these seven locks and, though in a poor state, is CADW listed. In 1949 it had, as Wright says, ‘a canal workshop with a large undershot water wheel on the tow path side, and on the other side, a boat repair and building yard.’ Here the last Swansea Canal day boat, the ‘Grace Darling’ was built.

Wright and Penry had by now hit the wall. ‘Nine miles of portages around locks and so early a start had begun’, he says, ‘to have an effect on us. We were tired and the sight of this flight of locks was almost too much’. Wright had became so weary that he no longer wrote down the journey times. Help from some more local children saved them. ‘Three youngsters, who had begun to follow us, offered to help by carrying our paddles and gear to the top. The offer was as unexpected as it was welcome. I had expected opposition and abuse from the canal-side urchins on the Swansea but throughout our 11 mile voyage there was no unpleasantness whatsoever.’

Much cheered by this hospitality, Wright and Penry made the ascent in easy stages to Lock 22, only to be met by a landslip which had completely blocked the canal. They carried the boat once more. Then they bow-hauled her through the outfall of a colliery washery. Eventually, Wright was able to get back into the boat and Penry directed him ‘through shallow and tin-filled water to the bridge by Ystlyfera station.’ Then it began to rain.
They were now desperate for a camping place. It was, Wright says, ‘getting dark rapidly’. They paddled across the still magnificent three span Twrch Aqueduct into Breconshire (now Powys) though Wright is, by now, in no mood for architectural appreciation of any kind.

12. The Twrch Aqueduct, 2015.

Industry, once more, slipped into the distance. Their mood lightens and Wright discovers ‘the most delightful stone path bridge I had ever seen. The bridge was narrow and with a subtle reverse curve and took the towpath over a forgotten branch canal to the Ynyscedwyn Ironworks.’ ‘Cheswardine’ is made fast there and Wright reconnoitres for a place to spend the night. He tramps past another two locks before he finds one. He walks two hundred yards through wet grass to ask the farmer’s permission to camp there. He returns to Penry. ‘Accompanied by some muttering and groaning we carried ‘Cheswardine’ up to the spot, half a mile below the village of Ystradgynlais’. They assemble the tent. It was 8.00pm and they had covered 11 miles and passed 21 locks. I trust they slept well.

The next day’s travel, on Wednesday April 20th is, perhaps mercifully for the two men, a very short one. It is now dry and sunny. The two men carry the canoe past Lock 27 and paddle into what is to be the last navigable water in the canal. It is barely 100 yards long. Ahead they can see Lock 28. ‘Its top gate had gone and water poured in from the very long disused part of the canal which stretched for a further two mile to Hen Neuadd in Abercrave'. To mark the occasion, they enter the derelict lock and take some souvenir photos. They can go no further.

I fear I have none of those momentous last photos, but the completion of their difficult journey is marked by another chance meeting. Mr T. S. White, the retired canal manager, who lived alongside the lock, sees the canoeists and tells them that the ‘Cheswardine’ is the first boat to work up to Ystradgynlais in 30 years. ‘No one to his knowledge had ever been through the canal by canoe before,’ reports Wright. ‘Presumably’, he adds, ‘I would be the last person, too.’

The thought of canoeing back to Morriston Station is too much for Wright and Penry and the two men decide to leave ‘Cheswardine’ at Penygoraf Farm, which adjoined Lock 27. On April 30th, she is brought by road to Aberdulais on the Tennant Canal and from there worked down to Clyne on the Neath Canal. A few weeks later, Wright begins an exploration of these two disused canals.

Though the condition of the Swansea Canal was no worse than many others in 1949, any hope of the Inland Waterways Association getting behind a push to restore it, is quashed by the linear nature of all the South Wales canals. They are unconnected to each other. The IWA is a small organisation in the nineteen forties and only the Brecon and Mon in South Wales receives concerted support. The Swansea Canal declines for another thirty years and it is only when no more than 5 of its original 16 mile is left in water that the mood turns. The Swansea Canal Society is formed in 1981, and the Swansea Bay Inland Waterway Partnership now lobbies for a 32 mile navigable waterway linking the Neath, Tennant and Swansea Canals via the Tawe river and the Prince of Wales Docks.

Wright’s voyage and report on the Swansea Canal may have had no immediate effect on its decline but his 1977 book ‘Canals In Wales’ with many of his 1949 photos, is a classic. ‘1949 was’, Wright says in its introduction, ‘a vintage year. I crossed the aqueducts over the Neath, cruised by Neath Abbey, portaged my way from Newport to Brecon, and became the last ever voyager up the Swansea Canal.’

One day, in the not too distant future perhaps, when two short, piped sections of the Swansea Canal are once more in water, and a seven mile unhindered stretch of navigation is created, it would be fitting to have a commemorative canoe trip (complete, of course, with the exhausting portages and, we hope, the helpful urchins) from Clydach to Ynysmeudwy to remember his pioneering work for the IWA.

40 Mlynedd o Wirfoddoli: Clive Reed a Chamlas Abertawe.

40 Years of Volunteering: Clive Reed and the Swansea Canal

Clive Reed yw Swyddog Treftadaeth Cymdeithas Camlas Abertawe. Mae ei wybodaeth a'i angerdd am Gamlas Abertawe heb ei ail. Mae eleni (2021) yn nodi 40 mlynedd ers i Clive ymuno â Chymdeithas Camlas Abertawe ac mae'r hanes Cymreig hwn o'i gyfraniad i Gamlas Abertawe hefyd yn dyst i'w gariad at yr iaith. Mae'r cyfieithiad Saesneg yn dilyn y cyfrif Cymraeg hwn.

Clive Reed is the Heritage Officer of the Swansea Canal Society. His knowledge of and passion for the Swansea Canal is unsurpassed. This year (2021) is the 40th anniversary of Clive joining the Swansea Canal Society and this Welsh account of his contribution to the Swansea Canal is also a testament to his love of the language. The English translation follows the Welsh.

Mae Clive Reed wedi gweithio ar, ac wedi ymgyrchu dros, i adfer Camlas Abertawe ers 40 mlynedd. Pan ym 1980, yn 37 oed, symudodd i fwthyn ar ochr y gamlas, roedd y ddyfrffordd mewn cyflwr gwael. O’r un ar bymtheg milltir gwreiddiol, dim ond y pump canol oedd ar ôl mewn dŵr, ac roedd y rhain hyd yn oed yn ddiffaith.

Yn 1981, ffurfiodd selogion camlesi Gymdeithas Camlas Abertawe. Ymunodd Clive â nhw. Trefnodd grwpiau gwaith wythnosol, gan ddefnyddio ei sgiliau a’i gysylltiadau yn Nociau Sych Abertawe i fenthyg, prynu neu logi offer. Bob dydd Sul o 1983 roedd yn gweithio gyda phartïon o 12/14 o wirfoddolwyr. Gyda chyllid gan Ymddiriedolaeth y Tywysog Cymru a chefnogaeth gan y Rhaglen Gwaith Cymunedol, trawsnewidiodd Clive a’r gwirfoddolwyr y gamlas rhwng Clydach ac Ynysmeudwy yn amwynder cyhoeddus.

Ailadeiladwyd pum milltir o lwybr tynnu, adferwyd dyfrbontydd ar y gamlas, ac yn Ynysmeudwy, ailadeiladwyd cwt olaf y ceidwad clo sydd wedi goroesi ar y gamlas. Roedd Clive yn hwyluso mynediad i’r peiriannau trwm trwy ddefnyddio pren wedi cwympo i greu trac.

Yn 1984 daeth yn Ysgrifennydd y Gymdeithas, gan aros yn ei swydd tan 2008, gan ysgrifennu cylchlythyrau rheolaidd a chynhyrchu taflenni, gan gynnwys yr unig lyfryn camlas tairieithog yn y DU. Ar hyn o bryd mae’n ysgrifennu erthyglau ar gyfer gwefan y Gymdeithas.

Yn 1993 trefnodd Clive y cynhyrchiad fideo Daucanmlwyddiant y Gymdeithas, ‘Towards 1994′, sy’n dal i gael ei arddangos yng Nghanolfan Treftadaeth Clydach, ar bwys y gamlas.

Yn 1992 rhoddodd Dyfrffyrdd Prydain hopiwr mwd segur i’r Gymdeithas. Gyda grŵp bach o wirfoddolwyr y Gymdeithas, gydag arian oddi wrth lawer o’r aelodau, gyda defnydd o dyluniadau Clive ac ar ôl dwy flynedd o waith caled, wnaethon nhw drawsnewid y gragen yn gwch trip o’r enw ‘David Papa Thomas’.

Rhwng 1991 a 1993 trefnodd garthu’r gamlas o Ynysmeudwy i Bontardawe ac felly erbyn 1994 gallai’r cwch deithio’r rhan hon gyda theithwyr. Hyfforddodd Clive chwe aelod o’r gymdeithas fel capteiniaid. Peidiodd y cwch â chludo teithwyr ar ôl 2005 ac, yn anffodus, cafodd ei ddinistrio yn 2006 pan roddodd ar dân gan fandaliaid.

Rhwng 1985 a 2005, bu Clive yn ymladd yn llwyddiannus yn erbyn datblygiadau Awdurdod Lleol, er mwyn amddiffyn coridor y gamlas i’w hadfer yn y dyfodol.

Yn 1994 ysgrifennodd Clive y geiriau i fynd gyda’r arddangosion a’r arteffactau a welwyd yng Nghanolfan Treftadaeth Coed Gwilym wrth ymyl y gamlas. Roedd hefyd yn ymgynghorydd ar y dyluniad a’r cynllun.

Er mwyn symud ymlaen i adfer Camlas Abertawe, daeth Clive yn Ysgrifennydd Fforwm Adfywio Dyfrffyrdd Integredig Abertawe, Nedd a Tennant yn 1998. Parhaodd y Fforwm am wyth mlynedd.

Ymddiswyddodd Clive fel ysgrifennydd y Gymdeithas yn 2008 trwy ddirywiad iechyd. Dyfarnwyd iddo Aelodaeth Oes y Gymdeithas ddwywaith, yn1992 ac yn 2008, ac mae bellach yn Gynghorydd Treftadaeth y Gymdeithas. Ers 1985 mae wedi rhoi, ar gyfartaledd, 15 o sgyrsiau darluniadol y flwyddyn ar waith adfer treftadaeth camlesi ac mae’n bwriadu parhau. Ysgrifennodd ‘Two Centuries of Pontardawe 1794 to 1994′, mae’n gyd-awdur o dair cyfrol o ‘Around Pontardawe and District’ ac yn ymgynghorydd ar gyfer y cyhoeddiad sydd i ddod sef, ‘The Swansea Canal and its Railways.’

Heb Clive Reed gallai Camlas Abertawe fod yn ddiffaith o hyd.

Clive Reed has worked on, and campaigned for, restoration of the Swansea Canal for     34 years. When in 1980, aged 37, he moved to a canal side cottage, the waterway was in a bad state. Of the original sixteen miles, only the middle five remained in water, and even these were derelict.

Clive & Eurig
In 1981, canal enthusiasts formed the Swansea Canal Society. Clive joined them. He re-organised weekly work parties using his skills and contacts as a craftsman in the Swansea Dry Docks to borrow, buy or hire tools. Every Sunday from 1983 he worked with parties of 12/14 volunteers. With funding from the Prince of Wales Trust and assistance from the Community Work Programme, Clive organised the transformation of the canal between Clydach and Ynysmeudwy into a public amenity.

Clive Reed Hut

Five miles of towpath were rebuilt, aqueducts on the canal restored and at Ynysmeudwy, the only surviving lock-keeper’s hut on the canal was rebuilt. Clive facilitated access for necessary heavy machinery using cleared trees to create a track wa

In 1984 he became Society Secretary, remaining in post until 2008, writing regular newsletters and producing leaflets, including the only three-language booklet about a UK canal. He currently writes articles for the Society’s website.
In 1993 he organised the production of the Society’s Bicentennial video ‘Towards 1994’, still shown in the Clydach Heritage Centre.
In 1992 British Waterways donated a canal mud-hopper hull to the Society and, together with a small group of Society members, funds from many other members and two years’ hard work, the hull was transformed, by Clive’s design, into the trip boat ‘David Papa Thomas’.

Clive welding DPT


 Between 1991 and 1993 he organised dredging of     the canal from Ynysmeudwy to Pontardawe so that   by 1994, the boat could travel this stretch with passengers. Clive trained six members of the societyas skippers.

The boat ceased to carry trippers after 2005 and,sadly, was destroyed by fire in 2006 by vandals.


Clive on DPT
From 1985 to 2005, Clive successfully fought against Local Authority developments, to protect the canal corridor for future restoration.
In 1994 Clive wrote the text for canal exhibits and artefacts displayed in the newly built, still functioning, canal-side Coed Gwilym Heritage Centre, for which he was also a consultant in its design and lay-out.
To progress the restoration of the Swansea Canal, in 1998 Clive became Secretary of the Swansea, Neath and Tennant Integrated Waterways Regeneration Forum for its 8 years’ duration.
Clive resigned as Society secretary in 2008 through declining health. He was awarded Life Membership of the Society twice, in 1992 and in 2008, and is now the Society’s Heritage Consultant. Since 1985 he has given, on average, 15 illustrated talks a year on the canal’s heritage and restoration work and plans to continue. He wrote ‘Two Centuries of Pontardawe 1794 to 1994’, is co-author of three volumes of the ‘Around Pontardawe and District’ series and a consultant for the forthcoming publication ‘The Swansea Canal and its Railways.’
Without Clive Reed the Swansea Canal might still be derelict.





Hafod Isaf Bridge







‘Swansea canal barge at the Hafod in 1931’

This is the caption for the finest historic Swansea Canal barge image known, and in the year 2000 publication of the book “Copperopolis” it is credited to the City and County of Swansea Museum Collection, but more of this later.
I assume the date 1931 was chosen because that was the date when the last official toll was charged for a barge travelling along the Swansea Canal with a chargeable cargo: carrying coal from Ynystawe to Clydach. Yet the photograph was posed at the Hafod Copperworks at Swansea, not at Ynystawe or Clydach as one would expect if that was the event photographed. Thereafter, after 1931, no commercial tolls were charged by the owners of the canal; at that time the Great Western Railway Company, because the cost of employing toll collectors, lock keepers and accountants was exceeding the cost of tolls charged, due the little commercial traffic on the canal.
However, barges did carry cargoes along the Swansea Canal into the mid-1940s, as statements made to me by Samuel Yateman Howard and Mrs Edwards relate. Sam Howard lived at Godre’r Graig and remembered the Swansea Canal working and carrying barge traffic along the canal from Pantyffynnon downwards to Pontardawe in the 1940s with cargoes of stone from local quarries. Mrs Edwards, living in Trebanos, and with whom I spoke in early 2000, also remembered canal barges passing along the canal at the bottom of her garden on several occasions in the early to mid-1940s. They were sheeted over so she could not see the cargo carried but the barges were fully laden.
We can surmise from these memories that the Swansea Canal did not carry its last commercial cargo in 1931. The mid section of the Swansea Canal, from the Hafod to Ystalyfera was still carrying barge traffic into the 1940s. The upper section north of Ystalyfera was no longer in use as a barge-carrying waterway and the section south of the Hafod was officially abandoned in 1928, although the photograph shows the G.W.R. to have carried out restoration/repair works to the Hafod Isaf Bridge on its lower down streamside. The upper side of the bridge is still in a ruinous condition so the bridge is undergoing restoration works. This would add to the date when the image was taken, to show that the canal was still operational northward beyond the abandoned section south of the Hafod. This suggests to me that this earlier year, 1928, would be when the G.W.R. took the photograph upon relinquishing their ownership of the canal to the south. But more of this later, I could be wrong in this assumption.
As for the photograph itself, the Swansea Canal Society also has a copy of this, donated when the society was formed in 1981, together with the information that this was the last barge to travel the Swansea Canal. The photographer had obviously printed more than one image from his negative. Unfortunately, the name of the photographer is not documented, nor is the name of the donor. However, when I took on the responsibility for canals exhibitions in the mid 1980s I showed this photograph to a professional commercial photographer in Pontardawe, Mr William Booth, who confirmed to me that the paper was genuine 1920s type photographic paper.
One of the founding members of the Swansea Canal Society was Sam Howard Yateman. I often sat with Sam and his wife Doreen at the Café on the Square in Pontardawe to have lunch. They told me so many stories of the canal, coalmining, quarrying, tinplate works and of Sam’s work as a fitter repairing machinery aboard ships at Port Talbot docks, at Plasmarl brickworks, Pontardawe steelworks and several other industries. Sam was a very skilled machinist in addition to being a marine and mechanical fitter. He made several accurate working models of a number of the machines he worked on or observed working. I was given Sam’s collection of live working models after he passed away. Two of those I later donated to the Waterfront Museum at Swansea. One was of a diesel driven stone crusher as used at Plasmarl brickworks, the other a twin cylinder horizontal steam engine similar to those at Pontardawe steelworks. They were all made by hand in his tiny kitchen at Godre’r Graig.
Of the many stories Sam related to me, one has a bearing on the canal barge that appears in this narrative. He said the barge was named “Grace Darling”. Sam was born in Godre’r Graig and had attended Godre’r Graig primary school until 1921 and after that at a junior school. In the Godre’r Graig primary school log book Sam Yateman Howard is recorded as being born on 10th May 1909 and living near Cilmaengwyn Shop. His father’s occupation is given as a boat maker and he worked at the Godre’r Graig boat building and boat repair yard, where he assisted Mr Thomas S. White, the Swansea Canal engineer, in building the Grace Darling. Sam used to take his dad’s lunch or sandwiches down to the yard and watch the men building the barge. After completion of the barge she was used in the Ystalyfera area as a maintenance boat. With so little barge traffic on the canal I do not understand why Thomas S White decided to construct a barge at all. However, he did do so and we are all very fortunate for that and for Sam’s memory of her name and the date of her construction - 1921.
The first question that comes to my mind is why he named the barge Grace Darling. This was just an ordinary canal boat, no bright decoration or cabin, just a plain canal barge. The answer to this question lies in the ancestors of Mr Thomas S. White. His father, Mr Thomas Richardson White, was born at Morpeth in the county of Northumberland. He was offered the position of canal engineer on the Swansea Canal. He spoke no Welsh, even though the region was mostly Welsh speaking at that time. A Swansea Canal Company advert placed in the Cambrian newspaper on 20th August 1858 said, “Wanted, a person to superintend the works on the line of the above canal – 16 miles. Experience of the nature of the employment is essential and a knowledge of the Welsh language is desirable”. However, he got the job. Mr Thomas Richardson White was canal superintendent from 1858 to 1905, when his son Thomas S. White succeeded him. The White family would have been very much aware of the exploits and bravery of the local Northumbrian heroine who saved the lives of a number of sailors shipwrecked on the nearby Farne Islands only about fifteen miles from Morpeth. Thomas S. White was probably remembering the birthplace of his father and added a little frivolity to an otherwise plain old workboat.
The story could have ended at this point but for another coincidence. I had put on display at Morriston library in 1992 a Swansea Canal exhibition. I received a telephone call from a lady who had seen the exhibition and she asked me if she could have a copy of one of the photographs displayed. I asked her which one and why. She wanted the one of the canal barge with the man and his horse because it was her father in the photograph. I arranged to visit the good lady the following week with a copy of the image as requested. I will omit the lady’s name for personal reasons. The story she told me was fascinating. William Henry Barnes 2
Her father was William Henry Barnes. He lived at Morfydd Street in Morriston and was an ostler working at “White Man’s Grave”. This turned out to be the local name for the Morriston Spelter Works and it had that notoriety because of the relatively high death rate at the factory, due to the very large volumes of zinc dust in the atmosphere inside the works. When asked why he was working on the canal, she told me her father loved working with horses. He normally worked at the zinc works for five days but on weekends he worked for a Morriston coal haulier delivering coal to factories along the canal. The barge in the photograph was the coal barge he used. She said without any prompting that the horse’s name was Zoe, but, when asked, couldn’t tell me the name of the barge. I knew the canal bridge was the Hafod Isaf Bridge (Hafod Lower Bridge, and I informed the lady of this and that the canal society knew the name of very few canal barges. One of those we knew was the “Grace Darling”. Immediately she said to me “That is that barge”, “It is Grace Darling”. I asked her how she could be sure of that. Her reply was honest and she showed relief that she had found out a part of her own family history.
It transpired that William Henry Barnes often told his wife that he was taking Grace out again on the weekend. His daughter (the lady I interviewed) thought for the rest of her life that her father was having an affair with a woman named Grace. It came as a relief to her to know it was only a canal barge and not another woman. I asked her if she knew the date the photograph was taken. She told me she could not remember the exact date the photograph was taken, but it was posed because that was the last day of the canal ferryboat working, possibly in the early 1920s.
A coal barge used as a ferryboat was new to me and of great historical interest. Mr Barnes used the coal barge on weekends ferrying workmen and women to factories along the route of the canal between Maliphant Street and Morriston. That was the section without any locks. The lady told me that trams were now working out of Swansea to Morriston, and it was a better way of travelling than on the coal barge. I was given a photograph of William Henry Barnes in addition to the wonderful story related above.
The barge in the photograph has a refinement not recorded on any other Swansea Canal barge. A rubbing strake has been added to the outside of the barge at mid section. This is probably because of the many times the barge rubbed against the canal masonry towpath when delivering coal to numerous factories. The lower strake of the barge appears to have been renewed or replaced. It is white in colour. The upper strakes have been painted with creosote or tar. There is no nameplate evident in the photograph.
There is no coal on the wharf alongside the canal to show that coal has been carried or unloaded, there are no wheelbarrows in sight to suggest that coal unloading has recently taken place, and the doors into the copperworks are closed, again showing us the viewer that no coal has been barrowed into the copperworks and the canal barge has not recently carried coal to this destination. So this brings me to the original question of when and why was the photograph taken. Was it 1923, 1928 or 1931? I would rule out 1931 and possibly 1928 although I have earlier proposed this date due to the fact that the G.W.R. might have been present to capture the last days of their ownership of the section of canal below the copperworks. So we are back to the original date I was offered of the last day of working of the canal ferryboat due to trams now operating out of Swansea and up to Morriston.
Why, when and by whom the photograph was taken, are fundamental questions in deciding the exact date of when it was taken and possibly by whom. The why and who has been proposed above. The “when” has also been slightly touched upon.
The date of the image is open to discussion. I have used the date 1923 during my talks on the Swansea Canal because of a suggestion by William Henry Barnes’ daughter that this might be the date when the ferryboat ceased working. However, a Swansea tramways researcher, Mr David Beynon, informed me during a discussion on this photograph that it had to be after 1928. In the image appearing in “Copperopolis” there is a name painted on the door at the right that gave entry to the Hafod Copperworks. The letters read as British Copper Manufacturers Limited. They took over the Hafod Copperworks that year. So the image could be any time after 1928. Where the Royal Institution obtained their date of 1931 is not recorded. I preferred the date then as 1928, not 1923.
I gave a copy of this information to the Royal Institution in 1993 and, a little later, a copy of the photograph to Gareth Mills who was a good friend of mine. I worked at Swansea Dry Docks when Gareth was shipping correspondent to the South Wales Evening Post and we both had an interest in Swansea bay shipping. On Gareth’s passing, sometime later, his collection of photographs, including those donated by colleagues, was given to The Retired Swansea and Port Talbot Dockers Association. I note that on their website Gareth’s collection was donated to Swansea Museum with the information that the collection was copyright of the above Association. I wish to correct this. Gareth would not have claimed copyright for a photograph he had not taken. Let it rest there.
To conclude this article on barge building at Godre’r Graig, another good friend, Mr Tom Williams of Pontardawe, obtained an interesting photograph c1980 of the Godre’r Graig barge-building yard. It shows a canal barge down stream of the yard and lock number 17. It has been estimated to be the early 1920 period.
All in all, this is a rather confusing conundrum to resolve. We know the name of the barge, the bargee, his horse, the location, why the barge was so named, why she operated as a canal ferryboat, the last days of various sections of the Swansea Canal operating as a commercial waterway, but as to the exact date of this intriguing photograph a question mark still exists. The photographer is unknown, although we know he made multiple images from his negative, yet these images appear in no local publications of that year.
So we are back to the last unanswered question. What is the date of the photograph? Is it 1923 as originally proffered or 1928 because of the name on the doorway into the copperworks, or 1931 as claimed on the Swansea Museum copy of this photograph? Personally I reject 1931 as the date because of the incorrect location of the last days of coal carrying which was at Clydach and not Swansea. So we have a decision to make on 1923 or 1928. I would prefer 1923 because of the ferryboat connection, but David Beynon threw a spanner into the works with his observation of the British Copper Manufacturers Limited sign on the copperworks doorway.
I welcome any suggestions from the membership of the S.W.W.I.A.S. Swansea Canal Society, Swansea Museums Service, National Museum of Wales and the R.C.H.M.W.

Birth of a Valley Project


Cast our minds back 400 years. The Swansea Valley was barely inhabited; there were no towns or villages as at present.  There were a small number of gentry houses such as Ynysdawe, Cilybebill, Ynyscedwyn, Hen-Neuadd, and possibly a few dozen farms.

Then it all began. A furnace was erected at Ynyscedwyn to produce iron, which was followed by coal mining to fuel the furnace, and forges to convert the iron into a workable metal. The iron was transported by packhorse to the forges at Clydach and Llandyfan, and by the donkey trail to the port of Neath. It all changed in 1794-98. the Swansea Canal was constructed to carry the mineral wealth of the valley down to Swansea.


















Canal tolls.    Charged at one ton per mile carried.

Coal                One penny per mile.                            Iron     Two pennies per mile.

Stone               Three half fence per mile.                   Pottery Two and a half pence per


Bricks             Three half pence per mile.                               Hay Two and a half pence per


Copper           Two and a half pence per mile.                       Lime   One penny per mile.

Nails                Two and a half pence per mile.                       Sand   Three half pence per mile.

Tiles                Three half pence per mile.



A barge laden with 22 tons of coal, travelling from Ystalyfera to Swansea in 1850, a distance of 12 miles, was charged a toll of £2-2-0, two pounds two shillings. The equivalent of £400-00 in today’s money (one week’s wages).






Discover the Story of Industrial South Wales


  1. Ynyscedwyn Ironworks. David Thomas discovered the method of using anthracite coal to smelt iron-ore in 1837. He emigrated to the USA that year and founded the American anthracite iron industry. The Literary Album of America said this of David Thomas in 1869, “Probably no man has done more for the permanent prosperity of the United States than Mr Thomas, and his efforts of enterprise, together with his high moral character, entitle him to a distinguished place among our useful citizens”.
  2. In 1858 the largest combined iron and tinplate works in the entire world was at Ystalyfera.
  3. The Twrch Aqueduct on the Swansea Canal was among the first in the UK to be constructed using hydraulic mortar.
  4. The thinnest iron in the world was rolled at the Pontardawe ironworks in 1871after a challenge from the USA ironmasters.
  5. The roofing plates of the White House in the USA were manufactured at the Pontardawe Steelworks circa 1908. The plates were lead-covered steel sheets known as TERNE plates.
  6. Swansea Canal. 18,000 barges a year passed along the Swansea Canal in the 1880’s.
  7. One of the first of the “new” towns in Wales. Created by the Morris family in the 1750’s.
  8. Swansea. The first reinforced concrete building to be constructed in the UK was the Weaver’s flour mill.







Swansea Valley heritage structures


Ynystawe Patent Fuel Works (Swansea Valley)

Ruins of the former experimental Patent Fuel works survive south of Clydach in the Swansea Valley. The works were erected circa 1875 by the Graigola Colliery Company to utilise waste poor quality coal. The coal was mixed with pitch and compressed at high pressures to form ovoids and brickquets. Ruinous masonry walls survive among the overgrown site.

A public cycle path runs through the site.

Swansea Canal toll-bridge at Clydach

Grade 11 Listed iron bridge erected by the Swansea Canal Company circa 1850 for the use of canal company employees. Later used by colliers and other workers to access factories and coalmines on the east side of the Swansea Canal. The canal company charged the workmen a toll of a half penny each way to cross the bridge. Later this toll was paid by the colliery company at two shillings and sixpence per year per man. The bridge is known locally as Pont John, and is the only known example of a toll bridge crossing a canal in South Wales.

There is public access over the bridge but the access path is steep and may be difficult for disabled persons.

Swansea Canal

Constructed between 1794/98 and running the length of the Swansea Valley between the port of Swansea in Glamorganshire and a place known as Hen Neuadd in Breconshire. Hen Neuadd subsequently developed into the village of Abercraf. The Swansea Canal was originally 16 miles long and constructed to access the coal reserves of the mid and upper Swansea Valley. Twenty Two coal mines were eventually opened along the line of the canal along with extensive iron works, tinplate works, copper works, foundries, potteries, brickworks, chemical works and steel works. All the settlements in the Swansea Valley developed around those industries.

The Swansea Canal was abandoned in several stages between 1928 and 1965. Only six miles remain at present between Clydach and Ystalyfera. The remaining canal sections are open for public access.

A Grade 11 Listed structure comprising a boat building yard and a canal lock. The lock was number 17 along the Swansea Canal. The boat building and boat repair yard was operated by the Great Western Railway Company (owners of the Swansea Canal from 1872) until circa 1930. The last Swansea Canal barge to be constructed was at this boat yard in 1918 and named “Grace Darling”, with boat repairs continuing until the 1930’s. The complex is very overgrown and difficult to access.

The Squeezed Lock at Pantyffynnon Ystalyfera

Lock number 18 in the Swansea Canal numbering sequence constructed 1795/96. The lock last passed barges circa 1930. The lock was originally about eight and half feet wide but due to geological pressure from the neighbouring mountain Allt y Grug the lock has been squeezed to a width of only seven feet wide along most of its length.

The lock is not operational.

The structure cab be viewed from the public footpath adjacent.

Ystalyfera Ironworks

Ystalyfera Ironworks was constructed by Benjamin Treacher and Evan James of Swansea in1838 with a single blast furnace, and enlarged by James Palmer Budd over the following 20 years to become the largest combined iron and tinplate works in the world (1858). The works was owned by James Palmer Budd ironmaster from1839 to 1885, and eventually was to consist of 10 blast furnaces, 42 puddling furnaces, 16 rolling mills, tinplate works, forges and collieries. The works declined during the late 1870’s and closed in 1885. Tinplate making continued until 1941.

The furnace charging platforms and retaining walls still survive, although now partially obscured by the new ASDA superstore erected against much local objections c2012. The town of Ystalyfera came into being as an industrial settlement to house persons employed at the works or its collieries. Many of the original industrial dwellings are still extant. These are private property with no public access.

Ystalyfera Ironworks waste tip

The iron waste of the works was used to reclaim land on the valley floor by creating an embankment of iron slag. The linear slag embankment contains hundreds of thousands of tons of iron slag and runs alongside the River Tawe for several hundred yards.

The tip is not suitable for public access, though it can be seen from the adjacent roadways.

Twrch aqueduct Ystalyfera

A Grade 11* Listed three-arched canal aqueduct with an attached culvert, built between 1794 and 98. The aqueduct was the largest structure built on the Swansea Canal and took approximately four years to build. The aqueduct carried the Swansea Canal over the Twrch River and out of Glamorganshire into the county of Breconshire. The structure is reputably the earliest known example of the use of hydraulic mortar in canal engineering. The aqueduct was known locally as Capitol Bridge after the adjacent Capitol cinema that operated during the 1930/60’ period.

The aqueduct no longer carries water. It is accessible via the former towpath which forms part of a public footpath.

The canal through Ystalyfera was drained during the mid 1950’s.

Cambrian Mercantile Colliery

Two 19th century engine-houses of the former Cambrian Mercantile Colliery Company, situated on the flank of Mynydd Marchywel near Varteg Hill Ystalyfera. The engine houses originally housed steam winding engines that were used to lower coal drams down to the valley floor to the railway sidings below.

The former tramroads offer access to the engine houses, but it is not suitable for disability access.

Ynyscedwyn ironworks Ystradgynlais

Remains of the ironworks buildings consisting of a chimney stack, and a masonry and brick multi-arched structure.  The buildings were part of the proposed ironworks conversion to a steel making programme of 1872 but never completed. Adjacent are a number of industrial artefacts associated with the Ystradgynlais area.

Ynyscedwyn Ironworks commenced in 1620 as a charcoal fired furnace. By the end of the 19th century the furnace was using coke as a fuel and producing 1498 tons of iron per week. A second furnace was built in 1830 that used anthracite coal as a fuel. Seven blast furnaces were erected by 1856 along with beam blowing engines to provide the blast for the furnaces. Iron making ceased at the works in 1876, but tinplate making continued until 1941.

There is public access onto the site.

Donkey trail

The route by which iron was conveyed to the port of Neath in the 18th century. The route commenced at Ynyscedwyn ironworks and followed the River Tawe southwards for about one mile before climbing the Varteg Hill to Cilybebill. The track was narrow and steep and mules with pannier baskets attached would have been used to carry the iron. Richard Parsons, the Ynyscedwyn iron master 1760-90 is recorded as paying twelve shillings per ton for carrying iron from his works to Neath. The mule-train drivers were paid eight pence per day.

The track is difficult to access due to the steep nature of the mountainside. Not suitable for disabled access.

Ynyscedwyn Branch Canal Ystradgynlais

Ynyscedwyn ironworks owned, private branch canal connecting the Ynyscedwyn ironworks to the Swansea Canal. It was constructed circa 1828. The branch canal is presently dry. The Swansea Canal has been infilled at Ystradgynlais leaving the branch canal as an isolated industrial monument.

There is public access along the former branch canal.

Claypon’s Engine House

A steam operated tramroad incline running up the western slope of Mynydd y Drum. The incline was designed by William Brunton as an extension to the Brecon Forest Tramroad system in 1832/34. Claypon’s tramroad (Joseph Claypon) commenced at Ystradgynlais and climbed up the Drum Mountain to reach the Dulais Valley near Onllwyn. The tramroad was horse-drawn on the level sections with the incline worked by a steam engine at the top of the incline. The steam engine was supplied by the Neath Abbey ironworks and was installed in an engine house known locally as “the machine”.

The incline has public access, but it is difficult for disabled access.

Abercraf Ironworks

The first purposely built iron furnace in the world to use anthracite coal as a fuel to smelt iron ore. Constructed by Daniel Harper in 1824 at the head of the Swansea Canal, the works used water from the River Tawe to drive its 35 feet diameter waterwheel, which provided the blast for the furnace. Surviving features include the charging bank, water leat, part of the furnace hearth and a bear of iron, wheel pit and workers cottages.

The site is overgrown and accessible with difficulty at the present time.

Cribarth Limestone, Silica and Rottenstone Quarries

Extensive industrial remains on the Cribarth Mountain near Abercraf, and consisting of ten miles of engineering features such as tramroads, causeways, inclines and quarries.  They were designed to exploit the mineral resources of the mountain, such as silica sand, Rottenstone and limestone. The limestone was used for industrial and agricultural purposes, the silica for brick making and the rottenstone as a polishing agent for the tinplate industry and the jewellery trade.

A large part of the mountain and the structures are open to public access, but other sections are private property. The mountain is quite steep.

Penwyllt village, near Craig y Nos.

A former quarrying settlement which was created around the Penwyllt silica mines and brickworks. A number of workers dwellings survive and also the partial ruins of the brick kilns, limekilns and the track bed and the railway platform of the Neath and Brecon Railway. Extensive remains of limestone quarries, tramroads, cuttings, embankments survive over a wide area of the mountain. Most of the tramroads have public access. The  railway was originally constructed 1864 by the Neath and Brecon Railway Company, closed in 1964 but re-opened by Hobbs Quarries to service the limestone quarries. The famous singer Adelina Patti had her own waiting room at the station with her own private railway carriage.

I hope you can make sense of all this historical information.


I am sending you one of the Ynysmeudwy – Pontardawe canal trail leaflets I researched and wrote, and one of John Thomas Rees. Most of his life story is in the enclosed leaflet, but I knew his grand niece and she told me the story of how he loved music, and as a young colliery boy, saved up his pennies until he had enough to buy a piano. He travelled down to Swansea from the little village of Cwm Giedd, purchased his piano and had it taken to the canal basin at Swansea. It was placed in a canal barge and carried back to Cwm Giedd. This boy later became a nationally renowned composer in Wales.
