name may come from the River Cam, as with the nearby villages of West Camel and Queen Camel. Other scholars suggest a derivation from some figure named "Cador" or "Cada". It is one of three sites in Somerset to include the Cadbury name, the others being Cadbury Camp, near Tickenham, and Cadbury Hill, which is also known as Cadbury-Congresbury to distinguish it from the other sites. Local tradition, first written down by John Leland in 1542, holds that Cadbury Castle was King Arthur's Camelot. The site and the Great Hall are extensive, and the writer Geoffrey Ashe argued that it was the base for the Arthur of history. His opinion has not been widely accepted by students of the period. Militarily, the location makes sense as a place where refugees and the southwestern Brythons of Dumnonia could have defended themselves against attacks from the east. If Arthur was indeed conceived at Tintagel, as tradition asserts, he may have been a prince of Dumnonia and used Cadbury as a stronghold on his eastern frontier. South Cadbury Environs Project The recent work on the archaeology of the site and the surrounding area has been carried out by the South Cadbury Environs Project. Since 1992 the project team, which included local volunteers South East Somerset Archaeological and Historical Society and the Yeovil Archaeology and Local History Society, have carried out geophysical surveys including gradiometry and electrical resistivity tomography, ploughzone sampling, test pits, deeper excavations and geographic information system (GIS) approaches. The project had input from academics and archaeologists from the universities of Bristol, Glasgow, Birmingham and Oxford, funded by the Leverhulme Trust and Arts and Humanities Research Council. The project studies the castle and surrounding area up to away, using landscape sampling, See also List of hillforts and ancient settlements in Somerset List of scheduled monuments in South Somerset History of Somerset References Bibliography Locations associated with Arthurian legend Hill forts in Somerset History of Somerset Tourist attractions in Somerset Scheduled monuments in South Somerset Structures on the Heritage at Risk register in Somerset
