Clive Engine House, Talargoch Mine

A large Cornish Engine House, about 13m by 11m., in axe-dressed uncoursed limestone masonry with ashlar arches to openings. Slate roof with a decorative wood finial surviving at the north apex; similar at south apex recently lost. The roof is of four bays with king-post trusses. The north (front) wall above tie-beam level is weatherboarded.

The bob-wall is to the north, about 2m in thickness, and continues up to about 6m below the level of the roof. The opening through this at ground level is arched. There is another opening beneath it at basement level, facing the very large circular shaft lined in brick and stone.

Four windows in the west wall with low segmental arches. East side ivy-covered but with a small opening at high level. The south side has a large central arched opening at ground level, with above that two beam bearings and a smaller central arched opening.
