Silbury Hill, Wiltshire England
The Heritage Trust
The largest man-made mound in Europe, mysterious Silbury Hill compares in height and volume to the roughly contemporary Egyptian pyramids. Probably completed in around 2400 BC, it apparently contains no burial. Though clearly important in itself, its purpose and significance remain unknown. There is no access to the hill itself.
Silbury Hill is part of the Avebury World Heritage Site, a Scheduled Ancient Monument and a Site of Special Scientific Interest. In order to preserve this site for future generations, we ask that visitors observe the no entry signs and do not climb or damage fences in order to avoid considerable damage to the hill.
