Stonehenge

Four, possibly five, Mesolithic postholes dated to around 8000 BC were found beneath the car park used by visitors until 2013; they had held pine posts about 0.75 m thick, three of them aligned east–west.

The first monument on the site, dated to about 3100 BC, was a circular bank and ditch some 110 m across with a wide north-eastern entrance; deer and ox bones, older than the antler picks used to dig the ditch, were laid in its bottom. Inside the bank were 56 pits, the Aubrey holes, named after the antiquarian John Aubrey. Between about 2900 and 2600 BC timber structures went up within the enclosure, at least twenty-five Aubrey holes received cremations and thirty more were placed in the ditch and elsewhere — the earliest known cremation cemetery in the British Isles.

Around 2600 BC the builders turned from timber to stone, digging the Q and R holes for up to 80 standing stones. The bluestones are generally accepted to have come from the Preseli Hills in Pembrokeshire, and quarrying evidence published in 2019 pointed to human agency rather than glacial transport. Between 2600 and 2400 BC thirty sarsens of about 26 tons each were brought from West Woods, 16 miles north, dressed with mortise and tenon joints and raised in a circle roughly 30 m across.

Analysis published in 2024 matched the Altar Stone not to Wales but to the Orcadian Basin of north-eastern Scotland, implying transport of some 430 miles. The bluestone settings of about 2280–1930 BC were poorly founded and began to fall over; the north-eastern arc was later removed to leave the Bluestone Horseshoe. The Y and Z holes, dug about 1600 BC, are the last known construction on the site.

More than 50,000 cremated bone fragments from 63 people were excavated in 2013 — remains buried originally in the Aubrey holes, dug up in 1920 by William Hawley, who considered them unimportant, and reburied together in 1935. A 2018 study of strontium in the bones found that many of those buried around the time of construction had probably come from near the bluestone source in Wales.

The monument is aligned on the midsummer sunrise and the midwinter sunset. Geoffrey Wainwright and Timothy Darvill have argued it was a place of healing, pointing to the number of burials and to trauma deformity in some graves; Mike Parker Pearson reads it instead as a domain of the dead, joined to the living settlement at Durrington Walls by the River Avon.

An excavation in 2008 suggested substantial Roman-era activity: late fourth-century coins, quantities of pottery and pit-buried bones of food animals. Hawley excavated a decapitated man aged 28 to 32 in 1926; radiocarbon dating places him between 600 and 690 AD. The grave was shallow, the body crammed in with most of its ribs broken and the head laid on top, and Mike Pitts reads the killing as sacrificial or judicial.

Geoffrey of Monmouth's twelfth-century Historia Regum Britanniae tells that the stones were healing stones brought from Africa to Ireland by giants and fetched to Britain by Merlin and Uther Pendragon as a memorial to British nobles killed by the Saxons. The tale is fiction, though Parker Pearson has suggested a grain of truth in it: the bluestones probably did come from a Welsh circle near the Irish Sea coast.

Stonehenge was sold at auction on 21 September 1915 as "Lot 15"; Cecil Chubb bought it for £6,600 and gave it to the nation three years later, having bought it on a whim, believing a local man should be the new owner. It had been legally protected as a scheduled monument since the Ancient Monuments Protection Act 1882.

A subscription launched in August 1927 to "save the skyline" raised £8,000 by that October, with George V as lead subscriber — enough to buy the plot holding Stonehenge Aerodrome and begin demolishing its hangars; the last large one came down in 1930. Sarsen 56 was straightened and set in concrete in 1901, and further stones were re-erected in concrete in 1958 and 1963. The site was added to the UNESCO World Heritage list in 1986.

Visitors could once walk among and climb the stones; they were roped off in 1977 because of serious erosion. English Heritage manages the monument and the National Trust holds the surrounding land, with access to the stones at the solstices and equinoxes and by special booking. The A344 closed in June 2013 and a visitor centre opened that December; the consent order for a road tunnel beneath the landscape was revoked on 17 March 2026, after £179.2m had been spent on its development.
