Kennet Avenue

West Kennet Avenue is a prehistoric stone avenue in Wiltshire, England, stretching 2.5 km between the Neolithic henge at Avebury and The Sanctuary on Overton Hill. Originally comprising approximately 100 pairs of standing stones spaced 15 meters apart, the avenue dates to around 2200 BC based on associated Beaker period burials. Stones were deliberately selected by shape -- tall cylindrical forms alternating with broad triangular ones, possibly symbolizing male and female. Today 27 upright stones remain, with 37 locations marked by concrete pillars from Alexander Keiller's 1930s restoration. The avenue is part of the Stonehenge and Avebury World Heritage Site.
