Avebury World Heritage Site


Avebury forms part of the only prehistoric World Heritage Site in England, recognised and protected by UNESCO. The Stonehenge, Avebury and Associated Sites World Heritage Property is internationally important for its complexes of outstanding prehistoric monuments.

Avebury prehistoric stone circle is the largest in the world. The encircling henge consists of a huge bank and ditch 1.3km in circumference, within which 180 local, unshaped standing stones formed the large outer and two smaller inner circles.  Leading from two of its four entrances, the West Kennet and Beckhampton Avenues of parallel standing stones still connect it with other monuments in the landscape. Another outstanding monument, Silbury Hill, is the largest prehistoric mound in Europe. Built around 2400 BC, it stands 39.5m high and comprises half a million tonnes of chalk.

The Henge at Avebury and Silbury Hill demonstrate the outstanding engineering skills which were used to create masterpieces of earthen and megalithic architecture. The boundary of the World Heritage Site was extended in 2008 to include East Kennet Long Barrow and Fyfield Down with its extensive Bronze Age field system and naturally occurring Sarsens.
