Positioned at the national grid reference 35960865, Hampton Down Stone Circle is located on the southern edge of an open downland ridge at a height of 680 feet above sea level. Located 1 kilometre (0.6 miles) north-west of Portesham on private land, it is positioned on the rim of Portesham Hill and overlooks the coast. Had the vegetation levels been low at the time of the circle's creation then it would have permitted extensive panoramic views of the coastline. The site is a scheduled monument, and thus accorded legal protection under the Ancient Monuments and Archaeological Areas Act 1979.
