Neath and Tennant Canals

Tennant Canal

The Tennant Canal joined the Neath Canal at Aberdulais Basin. Now derelict, it linked Swansea Docks to Aberdulais, and included the Red Jacket Pill Canal. There is currently a campaign to restore the Aberdulais Aqueduct, which is a Grade 2 listed structure; the adjacent Tennant Lock; as well as the weir that feeds water into the Tennant canal. It is hoped that the Canal will eventually be reconnected to Swansea Docks.

Neath Canal

The Neath Canal is still partially open. It linked GlynNeath to Giant’s Grave, and included the Briton Ferry Canal. Campaigning is underway to remove a road blockage in Neath centre and restore the lost canal between Abergawed and Resolven.
