Stonehenge, Avebury and Associated Sites

Stonehenge, Avebury and Associated Sites is a prehistoric complex of stone circles, henges, barrows and related monuments on Salisbury Plain and in surrounding Wiltshire, England. The World Heritage Site groups multiple major Neolithic and Bronze Age monuments under a single protective listing.

The core feature at Stonehenge is a circular arrangement of standing stones and trilithons with uprights and lintels; some stones stand about 7 metres high and weigh over 20 tonnes. The site includes a parallel ceremonial route called the Avenue that links the stone circle to the River Avon.

Beyond Stonehenge itself the World Heritage Site covers a wider prehistoric landscape. That landscape includes the large henge and settlement of Durrington Walls, the massive prehistoric mound Silbury Hill, the long barrow at West Kennet, and the much larger stone-and-henge complex at Avebury with its enclosure roughly 300 to 400 metres across.

The monuments were built in multiple phases in the Neolithic and early Bronze Age, with construction activities beginning around 3000 BCE and continuing into the second millennium BCE. The sites served ritual, funerary and ceremonial functions across centuries and were subject to later reworking, reuse and antiquarian interest.

The cluster of monuments lies on Salisbury Plain in Wiltshire; Stonehenge itself sits on the plain about 13 kilometres north of the cathedral city of Salisbury. The World Heritage Site spans a dispersed area that includes monuments in and around the Avebury area to the northwest.

• UNESCO status: Inscribed as a UNESCO World Heritage Site in 1986 as part of the 'Stonehenge, Avebury and Associated Sites' designation.
• Stone sizes: Some of the standing sarsen stones reach about 7 metres in height and individual blocks weigh in excess of 20 tonnes.
• Viewing note: The main monument is aligned to solar events, so sunrise and sunset at the solstices offer particularly notable light-and-shadow views of the stones.

What to See #

• Stonehenge circle: The stone circle and trilithons standing at the heart of the complex, with some upright stones and lintels reaching about 7 metres above ground and individual sarsen blocks weighing over 20 tonnes.
• The Avenue: A linear ceremonial route that runs roughly southeast from the stone circle toward the River Avon, visible as an earthwork and aligned with the monument.
• Durrington Walls: A large Neolithic henge and settlement immediately northeast of Stonehenge, formed by earthwork banks and ditches and covering several hundred metres.
• Avebury: A separate large Neolithic henge and stone circle about 30 km northwest of Stonehenge, with the henge enclosure measuring roughly 300 to 400 metres across.
• Silbury Hill: A large prehistoric mound close to Avebury, the biggest known prehistoric artificial hill in Britain at about 40 metres high.
• West Kennet Long Barrow: A long Neolithic chambered tomb near Avebury, surviving as an elongated earthwork and stone cairn dating to the prehistoric period.
