The photo is of the interior of this Neolithic chambered tomb which was built around 3650 BC. The burial chamber is only a small part of the whole barrow and comprises 5 smaller chambers: 2 on either side and 1 at the far end. Nearly 50 people were entombed here, dying within the space of 20 or 30 years, but the tomb was left open for 1,000 years  before it was sealed. Large stones ‘guard’ the entrance.

It is one of the most impressive and well-preserved burial chambers in Britain, and part of the Avebury World Heritage Site, close to Silbury Hill.
