NAR SH58SW1

One roundhouse can now be recognised of the straggle of four once recorded on the eastern side of the summit of Dinas, a limestone crag overlooking Traeth Bychan. RCAHM report that limpet, winkle and cockle shells have been foud here, together with animal bone fragments.
The Dinas crag comprises a generally level area about 110m north-south by 80m, surrounded by natural precipices on all sides. There is no evidence for a fort other than the name and the suggestive natural topography.
The roundhouses, depicted on the OS County series 3rd edition (Anglesey VIII.9 1920), ranged from 5.0m to 6.5m across, the surviving example, at the centre of the straggle, being one of the larger sort. To the north two roundhouses have been destroyed by a bungalow and the two southerly examples were too indistinct to survey in 1970.
Roundhouses such as these are characteristic of later prehistoric settlement in the region and have often yielded Roman material when excavated.
