- HILLFORT (Iron Age - 800 BC to 42 AD)
Erosion has removed the western side of the fort. The remaining defences consist of two lines of ramparts with a ditch between. The curve of the defences, together with what is known from early maps suggests that the fort was once a continuous enclosure. A simple entrance lies on the south-east side of the fort where cross-banks link the inner and outer ramparts to prevent access between. The eroding faces of the two ramparts show them to have been constructed from drift material, and partly faced with rounded boulders. The interior of the fort is relatively level, with numerous low earthworks and a single large raised mound that has been cut through.
The mound may be a Bronze Age barrow. Some of the other features have been interpreted as round houses, though other levelled areas may relate to the use as a gold course. Roman coins have been found on the site.
Large numbers of features are visible within the eroding section above the beach, from which it is clear the site retains significant archaeological remains which are being destroyed by erosion.
Prior to 2019 the hillfort had never been excavated although chance finds, suggest occupation in the 2nd-3rd centuries AD (coins and pottery) but its construction will have taken place considerably earlier. The fort is similar in construction, in certain respects to other local hillforts such as Dinas Dinorwig, Llan Ddeiniolen and Craig y Dinas, Llanllyfni.
