Stanton Drew Stone Circle-Although this is the third largest complex of prehistoric standing stones in England, the three circles and three-stone ‘cove’ of Stanton Drew in Somerset are surprisingly little known. The Great Circle, 113 metres in diameter, is one of the largest stone circles in the country and has 26 surviving upright stones. Yet recent surveys have revealed that the circles and cove were just part of a much more elaborate and important ritual site than had previously been imagined.
