Engine House On Site Of Grenville United South Mine

The engine house on the site of Grenville United South Mine is a tin mining engine house, likely built in the late 19th century, and is now derelict. It is constructed of coursed granite rubble and some killas, featuring quoins, a bob wall made of granite blocks, window arches of brick, and a chimney made of uncoursed rubble and brick; the building is currently roofless. It is situated on a raised terrace that runs east-west, overlooking the former dressing floor to the north. The structure has a rectangular plan oriented on a north-south axis, with the bob wall located to the north and the foundations of a former winding drum or fly-wheel in front of it. A circular chimney is attached at the south-east corner. The building consists of three stages, with round-headed doorways and window openings, and includes some tie-plates. The tapered cylindrical chimney lacks a cornice at the junction with the brick stage, much of which is missing. The foundations of the winding gear, made of large granite blocks, extend into the lower dressing floor. While the history was not known at the time of survey, the north side of the dressing floor features a long concrete wall with a doorway marked "W.G." and a medallion to the east inscribed with "1900 ONE AND ALL," along with another to the west labeled "FRUEL VANNER HOUSE 1901 C.F. BISHOP MANAGER."
