Another wonder of the Medieval World, the Stonehenge lies in the English county of Wiltshire, about 13 kilometres north of Salisbury. It has earthworks surrounding a circular setting of large-standing stones and is one of the most famous prehistoric sites in the world. It is estimated that the standing stones were erected around 3200 BC. Stonehenge is surely Britain's greatest national icon, symbolising mystery, power and endurance. Its original purpose is unclear to us, but some have speculated that it was a temple made for the worship of ancient earth deities. Others claim it was a sacred site for the burial of high-ranking citizens.
