Stonehenge

Stonehenge is a tourist attraction prehistoric monument located in the English county of Wiltshire, about 3.2 kilometres or 2.0 miles west of Amesbury and 13 kilometres or 8.1 miles north of Salisbury. One of the most famous sites in the world, Stonehenge is composed of earthworks surrounding a circular setting of large standing stones. It is at the centre of the most dense complex of Neolithic and Bronze Age monuments in England, including several hundred burial mounds.

StonehengeArchaeologists had believed that the iconic stone monument was erected around 2500 BC, as described in the chronology below. One recent theory, however, has suggested that the first stones were not erected until 2400-2200 BC, whilst another suggests that bluestones may have been erected at the site as early as 3000 BC. The surrounding circular earth bank and ditch, which constitute the earliest phase of the monument, have been dated to about 3100 BC. The site and its surroundings were added to the UNESCO's list of World Heritage Sites in 1986 in a co-listing with Avebury Henge monument. It is a national legally protected Scheduled Ancient Monument. Stonehenge is owned by the Crown and managed by English Heritage, while the surrounding land is owned by the National Trust.

Archaeological evidence found by the Stonehenge Riverside Project in 2008 indicates that Stonehenge served as a burial ground from its earliest beginnings. The dating of cremated remains found on the site indicate burials from as early as 3000 BC, when the initial ditch and bank were first dug. Burials continued at Stonehenge for at least another 500 years.Stonehenge was a place of burial from its beginning to its zenith in the mid third millennium B.C. The cremation burial dating to Stonehenge sarsen stones phase is likely just one of many from this later period of the monument's use and demonstrates that it was still very much a domain of the dead. Stonehenge evolved in several construction phases spanning at least 1500 years. There is evidence of large-scale construction on and around the monument that perhaps extends the landscape's time frame to 6500 years.

Archaeologists have found four, or possibly five, large Mesolithic postholes, which date to around 8000 BC, beneath the nearby modern tourist car-park. These held pine posts around 0.75 metres or 2 ft 6 inches in diameter which were erected and eventually rotted in situ. Three of the posts were in an east-west alignment which may have had ritual significance; no parallels are known from Britain at the time but similar sites have been found in Scandinavia. Salisbury Plain was then still wooded but four thousand years later, during the earlier Neolithic, people built a causewayed enclosure at Robin Hood's Ball and long barrow tombs in the surrounding landscape. In approximately 3500 BC, a large cursus monument was built 700 metres or 2,300 ft north of the site as the first farmers began to clear the trees and develop the area.

Stonehenge was produced by a culture that left no written records. Many aspects of Stonehenge remain subject to debate. This multiplicity of theories, some of them very colourful, is often called the mystery of Stonehenge. There is little or no direct evidence for the construction techniques used by the Stonehenge builders. Over the years, various authors have suggested that supernatural or anachronistic methods were used, usually asserting that the stones were impossible to move otherwise. However, conventional techniques using Neolithic technology have been demonstrably effective at moving and placing stones of a similar size. Proposed functions for the site include usage as an astronomical observatory, or as a religious site. Other theories have advanced supernatural or symbolic explanations for the construction.

StonehengeStonehengeAll the way through recorded history Stonehenge and its surrounding monuments have attracted attention from antiquarians and archaeologists. John Aubrey was one of the first to examine the site with a scientific eye in 1666, and recorded in his plan of the monument the pits that now bear his name.

A new landscape investigation was conducted in April 2009. A shallow mound, rising to about 40 cm or 16 inches was identified between stones 54 inner circle and 10 outer circle, clearly separated from the natural slope. It has not been dated but speculation that it represents careless backfilling following earlier excavations seems disproved by its representation in 18th and 19th century illustrations. A shallow bank, little more than 10 cm or 4 inches high, was found between the Y and Z hole circles, with a further bank lying inside the Z circle. These are interpreted as the spread of spoil from the original Y and Z holes, or more speculatively as hedge banks from vegetation deliberately planted to screen the activities.
