Compressor House and attached chimney at NGR SJ 3746 0213

The Compressor House and attached chimney, dated 1881, is located at Snailbeach Lead Mine. The building is constructed from regularly coursed limestone rubble with red brick dressings. It features a gable front roof, although the slates have been removed, leaving the purlins and rafters exposed, along with fretted bargeboards. The structure has a rectangular plan and consists of two levels.

On the front gable, there are two round-arched windows on the first floor, and a blocked doorway with a stone lintel is centered on the ground floor. An external staircase on the right side leads to another blocked doorway, which also has a stone lintel, and features a cast-iron balustrade at the top.

The attached chimney is located on the left side of the building and is made of engineering brick set on a rubble base. It has a square section that tapers towards the top, which is finished with toothed capping.

Inside, the first floor has been removed, but stone supports for the compressor remain. The roof structure features a king-post design with five bays. Originally, the compressor house housed two Siemens and Edwards compressors that supplied compressed air for rock drills and winches used underground.
