Large but little-known stone circle outside Stanton Drew, Somerset
Located in a field just outside the village of Stanton Drew near Bristol (OS Map reference: ST 601634), this is the second-largest stone circle in Britain, surpassed only by Avebury. The date of construction is not known, but is thought to be between 3000 and 2000 BCE. The Great Circle is 113 m in diameter and consists of 27 stones. There are two smaller circles – a 30 metre circle to the north-east with 8 stones, and a 40 metre circle to the south-west with 11. The site is on private land with no visitor facilities, so it is far less well known than its impressive size warrants. Admission costs one pound, to be placed in an honesty box.
