The stone circles have been studied since John Aubrey's visit in 1664, and some excavations of the site were performed in the 18th century. In the late 20th and early 21st centuries, geophysical surveys have confirmed the size of the stone circles and identified additional pits and postholes. The Cove has been shown to be around 1000 years older than the stone circles, and so date from 4000-3000 BCE. A variety of myths and legends about the stone circles have been recorded, including one about dancers at a celebration who have been turned to stone.
