History
Built in the mid-twentieth century, this building held explosives for mining activities. Big Pit was operated in connection with Blaenavon Ironworks, then by the National Coal Board from 1947 to 1980. Underground workings date from the early C19 but the shaft on this site was sunk in 1860. The present surface structures date from between c1900 and the 1970's. This piecemeal development was typical of mines in South Wales and it is now the most complete remaining, having been reopened as a museum in 1983.

Reason for designation
Included for its group value as an integral part of the process at this colliery site.
