Stonehenge, Avebury and Associated Sites was inscribed on the World Heritage Site List in 1986. It was one of the first seven sites to be nominated by the UK. Stonehenge and Avebury were nominated for their outstanding prehistoric monuments from the Neolithic and Bronze Age. They include Stonehenge (3000 – 1600BC), the most famous and sophisticated stone circle in the world, the immense henge and stone circle at Avebury and over 700 other monuments spanning around 2,000 years of history.
The Stonehenge and Avebury World Heritage Site is looked after and managed through a partnership of national organisations, the local authority, amenity groups, landowners, farmers and residents of the World Heritage Site.
Stonehenge, Avebury and Associated Sites is a UNESCO World Heritage Site located in Wiltshire, England. The WHS covers two large areas of land separated by nearly 30 miles (48 km), rather than a specific monument or building. The sites were inscribed as co-listings in 1986. Some of the large and well known monuments within the WHS are listed below, but the area also has an exceptionally high density of small-scale archaeological sites, particularly from the prehistoric period. More than 700 individual archaeological features have been identified. There are 160 separate Scheduled Monuments, covering 415 items or features.
The Stonehenge area of the WHS is located in south Wiltshire. It covers an area of 26 square km and is centred on the prehistoric monument of Stonehenge. Ownership is shared between English Heritage, the National Trust, the Ministry of Defence, the RSPB, Wiltshire Council, and private individuals and farmers.
The Avebury area of the WHS is located in northern Wiltshire. It covers an area of 22.5 square km and is centred on the prehistoric Avebury Henge.
