Portal To Engine Shaft At Cononley Lead Mine

The portal to the engine shaft at Cononley Lead Mine dates from around 1842 and is constructed of coursed rubble stone. The entrance walls are lined with dry stone walling, which rises to form a barrel vault over the door to the shaft. The walls taper in towards the door, and the stonework above the door is supported by iron and timber joists. This passage led into a shaft that was sunk to about 480 feet and served as the principal deep trail for the mine, providing access and a pumping way for the stopes located below the adit level. This structure is part of a group of lead mine buildings at Cononley that were erected by the agents of the Duke of Devonshire between 1842 and 1847.
