Site Overview

History & Significance

West Kennet long barrow is one of the largest, longest and most architecturally impressive Neolithic chambered tombs in Britain. Stretching 100 metres along a chalk ridge south of Silbury Hill, its mound covers five stone-lined chambers — two pairs of side chambers flanking a central passage — that served as a collective burial place for the community for over a thousand years after the tomb's construction around 3650 BC. At least 46 individuals were interred here, their disarticulated bones mixed and rearranged over generations in a practice that seems to have treated the dead as collective ancestors rather than individual people.

The monument forms part of the Avebury sacred landscape, visible from both Avebury and Silbury Hill and connected to the wider ritual complex of the Kennet valley. Its forecourt was a place of communal ceremony, and the tomb was finally sealed around 2000 BC with huge sarsen boulders and chalk rubble, effectively 'closing' a thousand years of ancestral burial. Stuart Piggott and Richard Atkinson excavated the chambers in 1955–56, finding the mixed bone deposits and associated pottery. The tomb is accessible to visitors, who can enter the chambers — a rare and extraordinary experience of a Neolithic interior.

Why it matters

One of the finest and most accessible Neolithic chambered long barrows in Britain, West Kennet provides direct evidence for Neolithic ancestral burial practices and forms part of the UNESCO World Heritage Avebury landscape.

Chronology

Historical Periods

Active Burial Phase
c.3650–2500 BC

Collective burial of at least 46 individuals. Bones disarticulated and rearranged, mixing generations of the dead. Grooved Ware and other pottery deposited with the dead.

Sealing
c.2000 BC

The forecourt blocked with massive sarsen stones and chalk rubble. A deposit of Beaker pottery, ox bones and flint placed in the blocking material.
