Along with the moai of Rapa Nui, Wiltshire, England's Stonehenge is one of the most famous mysterious structures in the world. Archeologists believe the ring of stone pillars with massive capstones perched on top was erected between 4,000 to 5,000 years ago. More theories and legends surround this place than any other prehistoric site on earth. There are no concrete facts pertaining to the purpose of Stonehenge, but many people think it is somehow religious and there is evidence that it was used as a burial ground at some point (human remains have been excavated from a ditch near the structure).
The most widely accepted theory is that it was a multi-purpose religious site for burial and worship of ancestors or deities. The south central part of England, where Stonehenge is located, was densely populated during the Neolithic Age and numerous burial mounds and artifacts have been found. This has allowed scientists to put Stonehenge in some sort of historical context if not to find answers as to its exact purpose and the method of construction. The site also has some significance to modern practitioners of the Druid faith.
