This ring of standing stones is one of the best known symbols of Great Britain in the world, as well as one of the greatest and mysterious monuments of all time. This prehistoric complex is located in Wiltshire, England, 2 miles (3 km) west of Amesbury and 8 miles (13 km) north of Salisbury.

The monument was most probably created with primitive tools by Neolithic Britons. Its estimated age varies from 4000 to 5000 years! It took Neolithic builders an estimated 1,500 years to erect. That's not surprising, as the massive stones, comprising the monument, weight from 4 to 25 tons!

And what about the purpose of erecting such an enormous construction? Many modern scholars agree it was a burial ground, but they still are tasked to determine what other purposes it served and, what is the most curious, how a civilization without modern technology—or even the wheel—produced the mighty monument.
