tells how the invading Saxon king Hengist invited British Celtic warriors to a feast but treacherously ordered his men to massacre the guests, killing 420 of them. Hengist erected Stonehenge on the site to show his remorse for the deed. Sixteenth century to present Stonehenge has changed ownership several times since King Henry VIII acquired Amesbury Abbey and its surrounding lands. In 1540 Henry gave the estate to the Earl of Hertford. It subsequently passed to Lord Carleton and then the Marquess of Queensberry. The Antrobus family of Cheshire bought the estate in 1824. During the First World War an aerodrome (Royal Flying Corps "No. 1 School of Aerial Navigation and Bomb Dropping") was built on the downs just to the west of the circle and, in the dry valley at Stonehenge Bottom, a main road junction was built, along with several cottages and a cafe. Stonehenge was one of several lots put up for auction in 1915 by Sir Cosmo Gordon Antrobus, soon after he had inherited the estate from his brother. The auction by Knight Frank & Rutley estate agents in Salisbury was held on 21 September 1915 and included "Lot 15.

In the late 1920s a nationwide appeal was launched to save Stonehenge from the encroachment of the modern buildings that had begun to rise around it. By 1928 the land around the monument had been purchased with the appeal donations and given to the National Trust to preserve. The buildings were removed (although the roads were not), and the land returned to agriculture. More recently the land has been part of a grassland reversion scheme, returning the surrounding fields to native chalk grassland. Neopaganism During the twentieth century, Stonehenge began to revive as a place of religious significance, this time by adherents of Neopaganism and New Age beliefs, particularly the Neo-druids. The historian Ronald Hutton would later remark that "it was a great, and potentially
