Clydach Limeworks (disused) are located some 250 metres SE of Clydach village. Limekilns stand on W side of quarry, prominently sited approximately 20m E of the Nant Dyar Viaduct.  

Industrial  

 

Late C19 limekilns, probably built for making mortar when the Merthyr, Tredegar and Abergavenny Railway (1862, closed 1958) was doubled in 1877: this involved widening the adjacent 8-arch Nant Dyar Viaduct . The limeworks was probably built when the railway was begun in 1862, for mortar and stone; another set of kilns located to the S (in deteriorating condition) is probably contemporary. Both kilns were served by a railway siding. By 1896, 30 men were employed at the quarry; 22 in 1944. The kilns ceased operation in the 1930s, but were refired during the war for agricultural lime, special hoods being made to place over the kilns during blackouts. The kilns finally ceased in 1955. After the railway closed in 1958, stone was brought by lorry, the quarry closing shortly after.  

Large rectangular kiln with battered walls. Rock-faced limestone construction. Some rock-faced copings remain. Paired round-headed drawing arches to left and right, set within shallow straight-headed recesses. Yellow brick arch-rings of three header courses. Small corner stoking-holes. Narrow central doorway with stone lintel leads to full-height straight flight of narrow stone steps to loading stage. Crucibles are infilled, but stair is still accessible.  

 

Listed as a large well preserved late C19 block of limekilns, a prominent survival of the important industrial landscape of the Clydach Gorge.
