Engine House And Attached Chimney

The engine house and attached chimney, dating from the early to mid-19th century, are located at Holmbush Mine in Stoke Climsland. The structure is built from roughly coursed slate stone with yellow brick dressings and features a slate roof adorned with ceramic cresting. The engine house has a rectangular plan, while the chimney is circular and tapers towards the top, attached to the west gable end. It stands two storeys high and includes two tiers of round-headed windows on the sides, along with a round-headed opening on the east gable end.

Inside, the engine house retains cross beams for the first floor at the west end and has a stone mounting for a former wheel. The roof features a collar truss design in four bays. This building was part of Holmbush Mine, which was first noted as a lead mine in the 17th century and later extracted copper and tin. Mining operations ceased in 1954, but the mine was reopened as part of Callington United Mines from 1888 to 1892.
