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.
Silbury Hill is part of the Avebury World Heritage Site, and a Site of Special Scientific Interest.

About 2350 BCConstruction Completed
After about 100 years the hill is completed as a much larger mound, surrounded by a massive ditch.
AD 43-410Roman Use
The Romans use the hill as a lookout while working on their new road from Mildenhall to Bath.
10th-11th centuriesDefensive Purpose
The top of Silbury is probably flattened and fortified, with a defensive building constructed on the summit.
A skeleton from the Saxon period is discovered during tree-planting on the summit.
Hugh Percy, 1st Duke of Northumberland, pays Edward Drax to dig a vertical shaft from the summit, expecting to find a central burial. Drax fails to find one.
John Merewether, Dean of Hereford, oversees the excavation of a horizontal tunnel.
Professor Richard Atkinson leads a major investigation for the BBC. He identifies three phases of hill construction.
2000An Unfortunate Legacy
A crater 14 metres deep opens on the summit. The excavation tunnels are found to be collapsing.
English Heritage commissions Skanska Civil Engineering to stabilise Silbury. Archaeologists briefly re-enter Atkinson's tunnel before 1,465 tonnes of chalk refill all voids.
