History

An engine house at Penprys colliery. It is associated with St David's colliery (a Scheduled Ancient Monument in Llanelli Rural community, near Penprys Uchaf, about 500m to the south). Penprys was one of the collieries acquired by the Llangennech Coal Company in the early C19. It was sunk in the late 1820s and worked intermittently until 1908. The engine house was built c1890 to house an engine taken from Old Castle Colliery (closed 1888), and probably constructed to the same dimensions as the house at Old Castle. The Penprys site is marked as 'old shaft' on 1918 Ordnance Survey 25" scale map. The set of engine beds related to it are believed to be intact and complete.

Exterior

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.

Interior

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