One more photo of the  Swansea Canal from Dominc Byrne. He says, “The photo shows the canal looking north up what is now the the Morriston by-pass from the Phelps and Williams tyre depot on the roundabout at the top of Beufort Road. The white building on the extreme left of the photo is the Swan public house”.

I assume the disused (?) station is Plasmarl.
