Grove Colliery Cornish Beam Engine House

A very large beam engine house of Cornish type, about 7 m by 10 m in plan. It faces N to the position of its pit, now capped. It is now roofless but the building is complete to its full height. Walls faced in squared limestone externally in irregular courses, but with a backing of local sandstone. The exception is the bob-wall, about 1.65 m in thickness, entirely in limestone. Above beam bearing level the masonry changes to larger courses.

There is a tall arched aperture to the front and a lower but wider archway to the rear. The arches are plain and of circular form. Smaller brick-arched openings in the side walls. Apertures internally for girders in the N and S walls. High-level window apertures at sides and rear, arched with backing lintels, and splayed sides.

Internally the building has been plastered, but some finished stonework internally indicates that it was originally fair-faced masonry.
