History

Dam, built 1840 to renew earlier structure. It was used to regulate the flow of water to Neath Abbey Ironworks some 1 km downstream. Water power was widely used in the works even after the advent of steam power. In 1840 the Neath Abbey Iron Company had two rolling mills and a boring mill powered by waterwheels. The Neath Abbey Ironworks were developed by two Quaker families, the Foxes of Falmouth from 1792 and Joseph Tregelles Price from 1817. Under Price the works became famous for high-quality engineering products including locomotives, stationary engines and steamships. The works closed in 1886.
