Stonehenge and Avebury became a World Heritage Site in 1986 for their outstanding prehistoric monuments which date from 3,700 to 1,600 BC. At Stonehenge, the unique lintelled stone circle is surrounded by a landscape containing more than 350 burial mounds and major prehistoric monuments such as the Stonehenge Avenue, the Cursus, Woodhenge and Durrington Walls.
The Stonehenge part of the World Heritage Site covers around 2,600 hectares and is managed by several landowners including English Heritage and the National Trust.
