The Neath Canal ran partly along one side of the river Neath and partly on the opposite side, the crossing being made by the aqueduct at Ynysybwllog. This was a fine and substantially intact six-arched structure until a flood in 1980 carried away the larger part of two arches and left the present ruin.
