Neolithic

Evidence of Neolithic settlement in Wales is extremely uncommon.

burial chambers are normally the only Neolithic structures to survive. However, an excavation of the site by Sabine Baring-Gould, in 1903, showed the remains of rectangular and circular Neolithic dwellings. An associated

has been dated to around 5500  years before present (BP), during the early to middle Neolithic. Sherds of Neolithic round-bottomed pottery, polished stone axes and animal bones were also discovered. Baring-Gould thought the pottery may have been wheel-turned. No hearths were found within the dwellings. However, "substantial" charcoal deposits were found on the site, indicating fire was used, and carefully managed. Samples from the area of Neolithic occupation (hut and midden), radiocarbon dated in 1973, indicated a date of around 2370 BP, the beginning of

The hill's steep sides were augmented by a single earthen rampart, to form a defensive structure known as a hillfort. The outcrop's southern part was further enclosed by stone walls, roughly rectangular, and measuring about by . Built as a

with stone blocks, the walls varied between and wide and were "faced externally with large slabs set on end". According to Baring-Gould, the enclosure's original surface was below its 1903 level. The enclosure's entrance may have been through a tunnel. Radiocarbon dated samples from near the hillfort entrance indicate a date of around 1950 BP (1 BCE), the late Iron Age.
