Clintsfield Colliery Engine House

Clintsfield Colliery Engine House is an early 19th-century pumping engine house that has been converted into a house and is now derelict. The building is constructed of sandstone rubble and retains a stone slate roof over the chimney. It features a main block that stands about 25 feet tall, with a lower shed attached on the north side, which has a capped chimney projecting from its western wall. The lower part of the east wall of the main block is made of large rock-faced sandstone blocks. There is a tall doorway with a stone lintel, although the upper part has been blocked with rubble since the conversion. The upper section of the wall, below the apex, is of rubble and includes a blocked beam engine opening with a round head, which now contains a smaller partly-blocked window. The south wall has two window openings with plain reveals, and under the apex of the west wall is another window with plain reveals. Inside, there are remnants of two floors and a first-floor fireplace with a plain stone surround. The adjoining shed on the north side appears to be built in the same style, although part of its wall at the north-east corner has collapsed. The chimney rises about 20 feet high, featuring rock-faced quoins and terminating with a rock-faced coping beneath a pyramid roof. This structure is likely the only remaining colliery engine house in Lancashire and was marked as such on the first edition 6-inch Ordnance Survey map from 1847. In 1839, it housed an engine of 5 horsepower along with a boiler and pump.
