Clydach Ironworks were built in the 1790s, and by 1841 there were 1350 people working here, day and night. The Ironworks closed in the 1860s, but industry continued for another century. Limestone was quarried for building stone and to make cement and lime, creating the rocky cliffs at the top of the valley that are still visible today.
The remains of the ironworks are now open for viewing, with parking and a picnic area on site.
The Ironworks were at the heart of a complicated network of horse-drawn tramroads. These brought limestone, iron ore and coal down from the quarries and mines and took the finished iron away to the canal at Gilwern. Steam trains arrived in the 1860s when the Merthyr, Tredegar and Abergavenny Railway was built, carving a spectacular route through the valley.
