The Stanton Drew stone circles are just outside the village of Stanton Drew in the English county of Somerset. The largest stone circle is the Great Circle, 113 metres (371 ft) in diameter and the second largest stone circle in Britain (after Avebury); it is considered to be one of the largest Neolithic monuments to have been built. The date of construction is not known but is thought to be between 3000 and 2000 BCE which places it in the Late Neolithic to Early Bronze Age.
