Description : The Clydach Ironworks, which were in operation by 1797, were located close to sources of iron ore, coal and limestone as well as water from the river Clydach and the confluence with the Nant Dyar (1988). The first furnace at the site was constructed in 1793 and the works started well producing 1,660 tons of iron in 1796. Edward Frere and Thomas Cooke operated the works, leased from the Duke of Beaufort. The blast furnaces at the site remained in production for over 65 years during which time the works were a focal point for much activity in the valley. In 1813 the site at Clydach boasted two furnaces, by 1833 this had increased to three with the blast supplied by a Boulton & Watt engine and a 42ft. wheel, while four furnaces were recorded for the first time in 1844. Clydach Ironworks was excavated and partly restored during the 1980s. Excavation revealed that the circular refractory brick linings survived up to the â€˜boshesâ€™ of the furnace stacks, while the dressed stone casings had been extensively robbed. Other remains on the site include a cast-house, charging houses and the wheel pit for a massive cast-iron water wheel 42 ft (12.8m) in diameter, which drove the blowing-cylinders (Roberts 2005).
