Stonehenge is a prehistoric monument located in the English county of Wiltshire, about west of Amesbury and north of Salisbury. One of the most famous prehistoric sites in the world, Stonehenge is composed of earthworks surrounding a circular setting of large standing stones. Archaeologists had believed that the iconic stone monument was erected around 2500 BC, as described in the chronology below, although this has since been advanced to 2400-2200 BC; however this was not the first stone structure on the site (see phase 3:1 below). 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, and it is also a legally protected Scheduled Ancient Monument. Stonehenge itself is owned by the Crown and managed by English Heritage while the surrounding land is owned by the National Trust.

New archaeological evidence found by the Stonehenge Riverside Project indicates that Stonehenge served as a burial ground from its earliest beginnings. The dating of cremated remains found that burials took place as early as 3000 B.C, when the first ditches were being built around the monument. Burials continued at Stonehenge for at least another 500 years when the giant stones which mark the landmark were put up. According to Professor Mike Parker Pearson, head of Stonehenge Riverside Project:

cquote: 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's 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.

Etymology

Christopher Chippindale's Stonehenge Complete gives the derivation of the name Stonehenge as coming from the Old English words "stān" meaning "stone", and either "hencg" meaning "hinge" (because the stone lintels hinge on the upright stones) or "hen(c)en" meaning "hang" or "gallows" or "instrument of torture". Medieval gallows consisted of two uprights with a lintel joining them, resembling Stonehenge's trilithons, rather than looking like the inverted L-shape more familiar today.

The "henge" portion has given its name to a class of monuments known as henges. Archaeologists define henges as earthworks consisting of a circular banked enclosure with an internal ditch. As often happens in archaeological terminology, this is a holdover from antiquarian usage, and Stonehenge is not truly a henge site as its bank is inside its ditch. Despite being contemporary with true Neolithic henges and stone circles, Stonehenge is in many ways atypical. For example, its extant trilithons make it unique. Stonehenge is only distantly related to the other stone circles in the British Isles, such as the Ring of Brodgar.Fact: date=September 2007
