The Clydach Ironworks site is situated in Clydach Gorge and consists of excavated and semi-restored ruins of a blast furnace. The works were built in the late 18th century and operated until 1860. They had a significant influence on the industrial and social development of the area:

Llanelly Quarry supplied the Clydach Ironworks with limestone, and subsequently lime.

Also in the area is a viaduct, limeworks, various tunnel mouths, another quarry, some arches, bridges, and more. If you’re interested, we came across this page detailing the Industrial Archaeology and History of the Southern Clydach Gorge.
