West Kennet Long Barrow
More than 300 feet long and one of the largest and most impressive Neolithic chambered tombs in Britain (though only about 50 people are buried here), the barrow was built around 3650 BC. You can explore the site and enter the tomb, which was used as a burial chamber for more than 1,000 years before the main passage was filled in and the front entrance blocked with sarsen boulders around 2000 BC. It has an elevated position with a great view of Silbury Hill and the surrounding countryside.
