Recorded by Liam Price on 18 March, 1932, "'The Druid's Stone' lies on the edge of the 'street'. It is covered on one side with cup-markings, an inch deep, some rather less, of different sizes. The largest is 5 inches across."
Price's sketch shows a stone 29 inches wide by about 2 feet tall with 20 cup-marks. I visited Threewells today, 14/9/07 and couldn't locate the stone. The area where I believe it once stood is totally overgrown.
