More information : A pump engine house to former tin mine, now derelict, built in 1888 for South Frances Mine. It is constructed from uncoursed granite rubble with a bob wall of large dressed granite blocks, window arches of polychrome brick, and a brick upper stage to the chimney. The building which now stands roofless, is of rectangular plan on a north-south axis, with the bob wall to the north and a chimney attached at the south-west corner. It has three stages, with mostly round-headed openings, including an unusually large driver's window in the bob wall, a large cylinder door in the rear wall, and unusual tall lancet windows (three in the rear wall, six and three in the east and west sides). The pump house was built to replace a former pumping system by flat-rod connections from Marriott's shaft; contained 80-inch cylinder powered by four (subsequently six) Cornish boilers. (1)
