Cornish Engine House of Penprys Colliery

The ruin of a small Cornish engine house built of local sandstone with dressings to the openings in brick. The masonry is informally coursed with dressed larger stones at the corners. Door openings at south and east. Windows at north and at high level in the east gable. Cambered arches with timber inner lintels. Some of the masonry on the west side has collapsed. The engine house survives for full height but is now roofless. Foundations of associated machinery have been recorded on the west side of the engine house, and are included in the Ancient Monument scheduling, but have been covered by undergrowth and tipping.

The basement is about 3m below ground level, with a central cross wall.
