Silbury Hill

Silbury Hill, the largest prehistoric mound in Europe, constructed during the third millenium BC, is overlooked by West Kennet longbarrow from the opposite side of the road between Marlborough and Devizes in Wiltshire, England, in the heart of crop circle country.

The St Mary Ley alignment of sacred sites which accompanies the St Michael alignment passes through here as described by Hamish Miller and Paul Broadhurst in The Sun and the Serpent.

Avebury is just a few miles north, while Stonehenge is further east.
