Stonehenge

(UNESCO: Stonehenge, Avebury and Associated Sites) Stonehenge and Avebury, in Wiltshire, are among the most famous groups of megaliths in the world. The two sanctuaries consist of circles of menhirs arranged in a pattern whose astronomical significance is still being explored. These holy places and the nearby Neolithic sites are an incomparable testimony to prehistoric times. © UNESCO World Heritage Centre.
