Archaeologists 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 is a place of pilgrimage for neo-druids, and for certain others following pagan or neo-pagan beliefs. The midsummer sunrise began attracting modern visitors in the 1870s, with the first record of recreated Druidic practices dating to 1905 when the Ancient Order of Druids enacted a ceremony. Despite efforts by archaeologists and historians to stress the differences between the Iron Age Druidic religion and the much older monument, Stonehenge has become increasingly, almost inextricably, associated with British Druidism, Neopaganism and New Age philosophy. Between 1972 and 1984, Stonehenge was the site of a free festival. After the Battle of the Beanfield in 1985 this use of the site was stopped for several years, and currently ritual use of Stonehenge is carefully controlled.
