This strange site with two enormous stones at the N of its perimeter stands at 100 m O.D. immediately to the S of main A35, 5 miles W of Dorchester. Its stones are a mixture of sarsen and conglomerate, of which there are many others in the neighbouring fields.
It is a small ring 29 ft 10 ins x 25 ft 11 ins (9.1 x 7.9 m) in diameter but its tallest stones, seven times the height of the others, stand directly at the north. Up to the 19th century there may have been a smaller stone in the gap between them.
The Nine Stones has no known counterpart in southern England. Only some rings in SW Scotland such as the Loupint Stanes (G7/4a), Ninestone Rigg (G8/2) and Burgh Hill (G9/15) seem comparable for they also possess two conspicuously taller stones, and it is of interest that there is a type of Scottish chambered tomb near the Nine Stones, at the Grey Mare & Her Colts (SY 583871) only 2| miles SW of the Nine Stones.
