Barratt's Incline, Grassington, North Yorkshire
This mine entrance was built in 1828 by Captain Barratt for the Grassington lead mines. Captain Barratt was the local agent and engineer supervising the lead mining from 1818. This was a time when a major reorganisation of the mines was taking place. He introduced sophisticated new techniques of ore dressing and invented the forerunner of the mechanical jig. The incline (slope) was driven into a 20 fathom network and introduced the use of ponies for drawing the ore out of the mine.
