Att South Cadbyri standith Camallate, sumtyme a famose toun or castelle. The people can tell nothing thar but that they have hard say that Arture much resortid to Camalat.
So wrote John Leland, an author attached to Henry VIII, in 1542.
In the summer of 1966 an archaeological organization began digging the hill of Cadbury Castle in the hope of finding some evidence which would substantiate that King Arthur was an ancient royalty and that Cadbury was his Camelot. The secretary of the organization was Geoffrey Ashe, who in Camelot and the Vision of Albion records his own personal search for the historicity of the legends of King Arthur and Camelot. The excavation of Cadbury established the possibility that Cadbury may have been a citadel of an Arthur-type figure, but nothing definite was found to substantiate that Arthur was an historical figure. The castle hill had earmarks of a stronghold of a wealthy leader who imported expensive goods. A “dark age knife” was found, also a dish marked with a Christian cross, some Tintagel pottery, and a bulk work three-quarters of a mile long, all of which indicated the “easy possibility” that this was the residence of a British Chieftain.
