Mysterious Stonehenge

From The Scotsman:

Stonehenge, a World Heritage site eight miles north of Salisbury in Wiltshire, is one of the world’s most famous prehistoric monuments, yet who built it and why remains a mystery. Its construction has been attributed to Celtic Druids, indigenous tribes from the late-Neolithic period and even the Arthurian wizard Merlin. Some believe it was a temple used to worship ancient earth deities. Others say it was a prehistoric astronomical observatory or a sacred burial site for people of high birth.
