Stonehenge

Stonehenge is a prehistoric stone monument on Salisbury Plain in Wiltshire, in the south of England in the United Kingdom, about two miles west of Amesbury. Built and rebuilt in stages from about 3100 BCE to about 1600 BCE by farming communities who left no writing, it combines a ring of huge sarsen uprights capped with lintels, an inner horseshoe of trilithons and smaller bluestones brought from Wales, all aligned on the midsummer sunrise and midwinter sunset. It stands at the heart of the densest cluster of Neolithic and Bronze Age monuments anywhere in England, hundreds of burial mounds among them.

Large pine posts were raised near the site around 8000 BCE, and in about 3500 BCE early farmers of the Neolithic built the long earthwork known as the Cursus nearby. The first Stonehenge, dated to around 3100 BCE, was a circular bank and ditch about 110 metres across, inside which lay a ring of 56 pits, the Aubrey Holes. Cremated remains of dozens of men, women and children were buried there from about 3000 BCE, and it is thought to be the oldest cremation cemetery yet identified in the British Isles.

Around 2600 BCE the builders turned from timber to stone. The bluestones, weighing about two tons each, are generally agreed to have been hauled some 150 miles from the Preseli Hills in Pembrokeshire, where ancient quarries have been found; work led by Mike Parker Pearson suggests some may first have stood in a circle at Waun Mawn. Between 2600 and 2400 BCE some 30 great sarsens, matched chemically in 2020 to West Woods about 16 miles to the north, were shaped with woodworking-style joints and raised in a circle, with five larger trilithons inside weighing up to 50 tons each. Research published in 2024 traced the sandstone Altar Stone to north-east Scotland, roughly 700 kilometres away. Over the next centuries the bluestones were rearranged several times, and the last known building work, the Y and Z Holes, dates from about 1600 BCE. At about the same time as the sarsens went up, the Bell Beaker people arrived from the continent, and DNA studies show they largely replaced the earlier population.

Why Stonehenge was built is still debated. Its solstice alignment is clear, and in the 1960s Gerald Hawkins argued that it worked as an observatory for tracking the sun and moon. Timothy Darvill and Geoffrey Wainwright have proposed that it was a place of healing, pointing to injured and far-travelled people buried nearby, while Parker Pearson sees it as a domain of the dead, linked by the River Avon to the timber circle at Durrington Walls, which he interprets as a place of the living.

Roman coins, pottery and animal bones show that the monument was still a focus of ritual in Roman Britain, though an older idea that the Roman army tried to destroy it has been discarded. A beheaded man buried among the stones in the seventh century may have been executed there. In the twelfth century Geoffrey of Monmouth wrote that the wizard Merlin had carried the stones from Ireland. In 1540 Henry VIII granted the surrounding Amesbury estate to the Earl of Hertford, and until the seventeenth century stones were removed for building.

John Aubrey surveyed the site in 1666 and William Stukeley, who linked it to the Druids, followed in the eighteenth century; the excavations of William Hawley in the 1920s and of Richard Atkinson and others in the 1950s set out the main building phases. Fallen stones were re-erected and set in concrete in 1901, 1958 and 1963. Stonehenge became a protected monument under the Ancient Monuments Protection Act 1882, and in 1915 Cecil Chubb bought it at auction for £6,600 and presented it to the nation in 1918. Public appeals bought the surrounding land, now held by the National Trust, while the stones themselves belong to the Crown Estate and are managed by English Heritage.

UNESCO inscribed Stonehenge with Avebury as a World Heritage site in 1986. Modern Druids have gathered there since 1905, and after years of exclusion following the 1985 Battle of the Beanfield, solstice access resumed around 2000. The stones were roped off in 1977, the road beside the Heel Stone closed in 2013 when a new visitor centre opened, and a long-running plan to put the nearby A303 in a tunnel was finally abandoned by the government in 2026.
