Grassington Moor contains extensive remains of lead mining, both above and below the surface. The moor is located to the north east of Grassington and as well as the mines themselves there are the ruins of ore processing works, drainage channels, engine houses, chimneys and the ropeways which once distributed power to the machinery.
The workings follow two main seams which run roughly parallel north west to south east. The importance of the area’s industrial history is recognised by a large part of it being a scheduled monument.
A local society - the Grassington Mines Appreciation Group - has been set up to help document and preserve the rich heritage of the area. Sub Brit made a donation to the group in 2021 to help protect some of the mine shafts; by securely fencing them they remain accessible to suitably equipped explorers. There are also plans to install interpretive signage.
