West Kennet Avenue follows a winding course of 1.5 miles, linking the Avebury Circles with the Sanctuary.
Originally consisting of about 100 pairs of stones, the Avenue followed a sinuous course. The stones were about 15 m (49 ft) apart and there was a span of about 24 m (80 ft) between the pairs. Several had been buried in medieval times, and others had been removed altogether. Of those remaining none were very large, between c1.4 m (5 ft) and 3 m (10 ft) high.*
The dating of the Avenue is probably slightly later than the main henge and circles, probably c 2300BC, although no absolute dating is yet available.*
