HER Info (unless otherwise noted)

The Ordnance Surveyors in the 1860s noted that this was an old mine shaft. It used to be the Delaval Coal Pit of the Old Hartley Colliery. This was sunk in either 1811 or 1812 and was worked until 1830. This and other collieries in the area were operated by Messrs. Ridley, Jobling & Co.
