Remains Of Large Engine House, Holmbush Mine

The remains of a large engine house at Holmbush Mine date from the early to mid-19th century. Constructed from roughly coursed slate stone with granite dressings, the building is now roofless and has a rectangular plan aligned north-south. It stands two storeys tall, although the gable at the north end is missing. The gable ends feature round-headed openings, with two round-headed windows at the apex of the south gable end, while the sides have rectangular openings. This engine house was part of Holmbush Mine, which was first mentioned as a lead mine in the 17th century and later extracted copper and tin. Mining operations ceased in 1854, but the mine was reopened as part of Callington United Mines from 1888 to 1892.
