South Cadbury Castle (N.G. ST 6225) occupies a free-standing hill, some 500 feet high, towards the Somerset-Dorset border. The hill itself is principally, if not entirely, of yellow sandstone belonging to the Jurassic series. To the west there are wide views across the low-lying Somerset basin centred on Glastonbury, an area of great importance in the early post-Roman centuries. To the east, a scarp marks the western edge of the higher ground of Wessex. In cultural terms, South Cadbury lies within the north-western limits of the coins of the Durotriges, but is only a dozen miles from the Glastonbury Lake Village. In the post-Roman period, it is one of the most easterly sites to produce imported pottery of Tintagel type, as well as one of the most inland.
