HISTORY: This part of the South Crofty Mine was re-organised between 1900 and 1908, and the current buildings represent the mine as it was by 1914, with the loss of the 1903-6 miners' dry to the S side. The steam engine was moved here from Tregurtha Downs. It includes the paired engine houses for pumping and winding, the compressor house and its chimney, and the extensive workshop provision for the mine. The persistence of mining into the C20 in the Camborne/Redruth area has resulted in a number of extraordinarily well-preserved complexes such as Taylor's Shaft at East Pool, King Edward mine and the Tolgus tailings works. This is the most complete surviving part of the South Crofty workings, the last working tin mine in Europe which closed in 1998, remarkable for its degree of preservation in a national context and with a range of buildings including the engine house and boiler house (qqv) which are strongly representative of C19 and early C20 mine workings.
