Western Pit worked coal and ironstone for the Butterley Company and later acted as a ventilation shaft for the nearby Britain Pit. Western Pit mined the Deep Soft Coal at 162 yards deep, the Deep Hard Coal at 188 yards deep, the Low Main Coal at 246 yards deep and the Black Shale Coal at 288 yards deep.

As far as I can tell this is the West Pit of the Butterley Park Colliery of the Butterley Company at Swanwick. Today it stands with adjacent engine house in the middle of a farm park where visitors can feed and watch a range of animals. I think that the colliery was open from 1848 to 1946 with the main shaft known as Britain Pit.
