A large and impressive Neolithic henge, much better preserved than neighbouring King Arthur's Round Table. Its banks stand up to 3 metres (10 feet) high, and unusually are constructed of pebbles collected from the nearby river.
Near the centre is a single standing stone: old drawings suggest that it was one of a group here, four more having been removed from the entranceway. Please note: Dogs on leads are welcome.
