West Kennet Avenue
West Kennet Avenue
West Kennet Avenue is a long, winding prehistoric arrangement, composed of parallel rows of standing stones, stretching the southern end of the henge at Avebury to The Sanctuary on Overton Hill, over 1.5 miles away. Over 100 pairs of stones still stand, most near the Avebury end of the Avenue.

The avenue seems to form some kind of a processional way, used for ritual observances. Quite what those observances are is anyone's guess.

The size of the stones varies quite markedly, from a high of 3.3 metres down to 1.6 metres. The rows are on average about 15 metres apart, and stones in each row are spaced at about 20 metres.

One theory suggests that the stones were alternating symbols for male and female, with larger, more upright stones representing males, and shorter, diamond-shaped stones representing females. That would suggest some sort of fertility aspect to the Avenue, but there is no solid evidence to prove this hypothesis.

A burial was found beneath one of the stones, and other possible burial sites in close proximity.

Near the Overton Hill end of the Avenue is an earthwork bank, which runs in a line for 320 metres. Though perhaps of medieval origin, this bank has been suggested as a being contemporary with the Avenue. Some investigators suggest that a cove, or semi-circular enclosure, once stood within the Avenue, but this suggestion is not universally accepted.

A similar avenue of stones, dubbed the Beckhampton Avenue, once ran from the western side of Avebury, though most of this avenue has been lost.
