The Outer Circle - The stones, each weighing about 40 tons or more, were left rough and not dressed (as the Stonehenge blocks were). The outer circle originally consisted of 100 stones, which  were obtained from the nearby Marlborough Downs. Now there are only 27 left, as many of the stones were broken up in the past, and used to construct the present village which grew up within the earthwork.

The Stones are believed to have alternated between 'Upright' and 'lozenge', possibly representing male and female.

The two smaller circles within the great ring were probably important ceremonial centres. Of the northern one only few stones are visible.

The Cove - Two of the central stones (once three), are called The Cove, and may have been erected first, even before the great circle. The same feature can be seen at Arbor Low.

The Fourth Circle - Although it is not commonly mentioned, a fourth circle has been shown to have once existed at Avebury. It was discovered in 1937 by 'A. Keiller', who found three 'unrecorded stone holes...eleven metres apart on the arc of a circle about 103metres in diameter, much the same as the 'North' and 'South' inner circles, whose stones were also placed about eleven metres apart. The centre of this third circle was on the same North-north-west to South-south-east axis as the others and Keiller concluded that "it seems impossible therefore not to conclude that what one may term as 'Avebury I' consisted of three settings of stones...unaccompanied by banks or ditches".

The Avenues - There were two ceremonial avenues of standing stones departing from the main ring. Only one survives, the West Kennet Avenue, which was originally 2.5km (1.5 miles) in length and connected Avebury to the small stone circle called The Sanctuary on Overton Hill.
