Prominent stone-buit contour fort located on Dinas outcrop overlooking sea to N. In area of outstanding prehistoric landscape from Neolithic. Surrounding slopes NE moderate, NW steep, S and W very steep. The outcrop is one of the sites of material for Craig Lwyd axes. Promontory much robbed for stone making interpretation difficult. Extensive rubble/scree slopes to W. Internal area 0.64ha. Defined by central enclosure c. 40m in diameter with central hut and two additional ramparts on S and one on N. Rampart walls c. 2.7m thick of loose stones faced with upright slabs, but only c. 0.3m high now. Traces of another 13 huts, 7-10m diameter, within these additional ramparts. Possibly later than ramparts. Partial excavation in 1925 by Harold Hughes and Beazant Lowe. Ramparts sectioned and central hut part-excavated producing evidence of paving, hearth and post-hole. No ditch. No dating evidence, but two quern fragments and fragments of a rubbing stone also found. Site much robbed of stone and walls now c. 0.3m high. Terraced fields and round huts and single long hut to NE, outside scheduled area. Rough upland grass and much bare rock and scree. On 1st Ed. OS map (1889). Undated.
