Erected between 3000 and 1600 BC, Stonehenge is a giant stone circle that stands on Salisbury Plain and is considered today to be one of the most famous surviving sites from the ancient world. The stones, which stand at 6.7m (22ft) high, attract hundreds of visitors every day, who come to marvel at the ingenuity of those who engineered the construction of the site and the techniques used to move and position the stones. There are also many burial mounds nearby, as well as long barrows from the Neolithic Age, the most famous of which is West Kennet Long Barrow. Visitors can also look forward to seeing the new Visitor's Centre where guests will be able to virtually 'stand in the stones', see 300 other prehistoric objects on display, and check out the museum detailing the various theories about how Stonehenge came to be.
