History

Small late C18 culvert, with overflow sluice, taking the Twrch Brook under the B4434 and the Neath Canal. The canal was originally planned from Pontneddfechan to Neath and was started in 1791 with Thomas Dadford Junior as General Surveyor. Thomas Sheasby replaced him in mid 1792 and the Neath Canal was completed in 1795. By 1799 the canal had been extended to the Giant's Grave near Briton Ferry.
