West Kennet Long Barrow

The West Kennet Long Barrow is a Neolithic tomb or barrow, situated on a prominent chalk ridge, near Silbury Hill, one-and-a-half miles south of Avebury in Wiltshire. The construction of the West Kennet Long Barrow commenced about 3600 BC, which is some 400 years before the first stage of Stonehenge and it was in use until around 2500 BC.
