History
Late C19 limekilns, probably c. 1860s or 1870s, being similar to kilns of that date at Clydach and Llanelly Limeworks. Blackrock Limeworks was in operation from 1794-1908, with kilns recorded in 1795. The quarries were located alongside the Clydach Railroad, begun in 1793 as a horse-powered railway between the Brecon and Abergavenny Canal and the new ironworks at Clydach. The railroad was one of several late C18 and early C19 industrial routes through the precipitous Clydach Gorge. The quarries supplied the ironworks with limestone for fluxing, and also provided building stone and burnt lime for mortar and agricultural purposes. In addition, ‘block’-stone was transported to the canal at Gilwern to be carted to various destinations for road-metalling. Coal for the kilns was brought in from Brynmawr via railroad. The present kilns were refired between 1941-43, when the quarries were purchased by Craig-y-gaer Quarries Ltd., employing 6 men in 1943, who produced 117 tons of burnt lime in April 1943.
