It has been suggested that the name of Amesbury is derived from Ambrosius Aurelianus, leader of Romano-British resistance to Saxon invasions in the 5th century. If this is the case he is likely to have used the hill fort as a stronghold. It is possible that an order of monks established a monastery in the area that was destroyed by the Saxons before they settled the area in the 7th century. Amesbury is also associated with the Arthurian legend: the convent to which Guinevere retired was said to have been the one at Amesbury.
