"William Pit, presumably a Coal Pit is shown on the 1st edition Ordnance Survey plan with a Chimney on the site." - Sitelines

NEHL - William Pit, otherwise known as the Cube Pit, was a shaft and outlet for gases drawn out by the ventilating furnace that sat in the mine. They were otherwise known as cube's, and they enabled pit workers to pass through to the bottom of the pit without being suffocated by noxious gases. Cube's were a predominantly Scottish term, but will have been passed down given the amount of Scottish pitmen who settled in the area for work. It can be presumed William Pit was part of Felling Colliery.

The name has been mistaken for Q Pit, though it was never formally called this.

There is no trace of the pit today.
