Remains Of Engine House, Holmbush Mine

The remains of an engine house at Holmbush Mine date from the early to mid-19th century. It is constructed of roughly coursed slate-stone with granite, purple, and yellow brick dressings and is currently roofless. The building has a rectangular plan aligned east-west and originally stood two storeys high, although the gable at the east end is now missing. There is a round-headed window on each floor of the west gable end, with rectangular openings on the sides. Holmbush Mine 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 re-opened as part of Callington United Mines from 1888 to 1892.
