It is now listed as part of the Stonehenge, Avebury and Associated Sites World Heritage Site.
) is a Neolithic henge monument containing three stone circles, around the village of Avebury in Wiltshire, in southwest England.
One of the best known prehistoric sites in Britain, it contains the largest megalithic stone circle in the world.
The available evidence suggests that in the early Neolithic, Avebury and the surrounding hills were covered in dense oak woodland, and as the Neolithic progressed, the woodland around Avebury and the nearby monuments receded and was replaced by grassland.
Evidence of activity in the region before the 4th millennium BCE is limited, suggesting that there was little human occupation.
Archaeological investigation followed in the 20th century, led primarily by Alexander Keiller, who oversaw a project which reconstructed much of the monument.
