Cadbury Castle is a hill fort near the village of South Cadbury in Somerset, England, five miles north west of Yeovil. The fort is one of the best known of the sites associated with mythic Arthurian England, and the legends of Camelot. The summit is 150 metres (500ft) above sea level, and the hill is surrounded by four terraced earthwork walls and a stand of trees. Excavation at and around the site has discovered iron age, Roman and Saxon artefacts. The limestone hill is situated on the southern edge of the Somerset Levels, with flat lowland to the north.
