Unusual hillslope hillfort located on a shelf on S slopes of narrow ridge within Coed Tan-yr-allt above Afon Conwy to W. Very steep to precipitous surrounding slopes which level out to river on W and on S, less to ridge top on N and E. Site D-shaped with ruinous, but still strong, dry-stone wall of rubble masonry to 1m high in places. No entrance visible. Site divided into three areas by natural crags. Small ditch in interior; possibly a foundation trench for some structure or tower of unknown date. To N of enclosure and cut across the ridge is ditch c. 1.5m deep, and to S of site edges of the ridge reinforced with poorly preserved stone walling, except on the NW. Possible entrance on S apex protected by additional walling at lower end. Possibly a medieval motte. Heavily afforested. Minimal investigations, undated.
