Village in Wiltshire, south-west England, the site of a Late Neolithic ceremonial complex, including a massive Henge and stone circle (see fig.; see also Prehistoric Europe, §IV, 2, (iv), (a); Megalithic architecture, 2). The Avebury monuments are close to the contemporary earthwork at Silbury Hill, the earlier causewayed camp at Windmill Hill and the megalithic tomb at West Kennet. Alexander Keiller excavated and partially restored Avebury in the 1930s.
At the centre of the complex is the great henge, consisting of a ditch (originally 9 m deep) and an outer bank. Sherds of Windmill Hill ware, Peterborough ware and Grooved ware pottery were excavated from the bottom of the ditch. No material from Avebury has yet been dated by radiocarbon analysis, but finds of these pottery types and comparison with other large henges in the locality (such as Durrington Walls) suggest that construction began after c. 2500
