The hill's steep sides were augmented by a single earthen rampart, to form a defensive structure known as a hillfort.^[3] The outcrop's southern part was further enclosed by stone walls, roughly rectangular, and measuring about 280 feet (85 m) by 100 feet (30 m).^[9] Built as a dry-stone wall, from stone rubble and earth, the ramparts stand about 2 feet 6 inches (1 m) above the enclosure floor.^[1][11] Revetted with stone blocks, the walls varied between 9 feet (2.7 m) and 15 feet (4.6 m) wide and were "faced externally with large slabs set on end".^[1][11] According to Baring-Gould, the enclosure's original surface was 2 feet 6 inches (1 m) below its 1903 level.^[11] The enclosure's entrance may have been through a tunnel.^[3] Radiocarbon dated samples from near the hillfort entrance indicate a date of around 1950 BP (1 BCE), the late Iron Age.^[6]
