Doulting Stone Quarry (grid reference ST648436) is a limestone quarry at Doulting, on the Mendip Hills, Somerset, England. At present there are only three quarries quarrying Doulting stone. The largest, The Doulting Stone Quarry, was producing building stone in Roman times. In the 20th century it was operated by the Keevil family. Until 1994 it was operated by Amalgamated Roadstone Corporation (now part of Hanson plc) but was then bought out as a stand-alone business. Ham & Doulting Stone Co Ltd own the east quarry which was originally in use for centuries after which followed a period of inactivity. It was reopened 12 years ago. The quarry also offers primary and secondary cutting and profiling.
