Description
The former Llanbradach Colliery upper revetment wall is a long and tall structure oriented north-south, extending from the engineering shop to beyond the fan house. It is built from snecked, rock-faced sandstone and features an irregular top, with most of its coping missing. Facing the former yard, there is a high-level segmental-headed doorway with steps leading up to the engine hall. To the left of this doorway, an opening at the top of the wall indicates the position of the winding cables from the engine hall to the shaft. Opposite the engineering shops, there is a round-headed opening that leads to a vaulted chamber. Another similar vaulted chamber can be accessed through a narrower segmental-headed doorway opposite the fan house. Girders connect the wall to both the fan house and the engineering shops, and several brackets project from the wall at high levels.
