Stonehenge is a prehistoric monument in Wiltshire, England. One of the most famous sites in the world, Stonehenge is the remains of a ring of standing stones set within earthworks. It is in the middle of the most dense complex of Neolithic and Bronze Age monuments in England, including several hundred burial mounds. Archeological evidence indicates that Stonehenge could have been a burial ground from its earliest beginnings. The dating of cremated remains found on the site indicate that deposits contain human bone from as early as 3000 BC, when the ditch and bank were first dug. Such deposits continued at Stonehenge for at least another 500 years. Throughout the 20th century, Stonehenge began to be revived as a place of religious significance, this time by adherents of Neopagan and New Age beliefs, particularly the Neo-druids. The site and its surroundings were added to the UNESCO's list of World Heritage Sites in 1986. Illustration not captioned or dated depicts a sheep herder with his flock in the ruins of Stonehenge.
