The monument complex of Thornborough in Yorkshire is an archaeological landscape of national and international importance and represents what would have been one of Britain's premier sacred landcapes during the third and second millenium BC. However that landscape is now at risk due to the expansion of quarrying.

The Friends of Thornborough group has been set up to raise the profile of, and protect the area around, the Thornborough henges in North Yorkshire.

Tarmac Northern Limited plan to extend their existing quarry around the henges and Thornborough Moor.
