Summary

Small, univallate, contour fort located near confluence of Afon Wrye and Afon Wyre fach above the coastal plain. Moderate to strong N surrounding slopes, E and S, moderate and W steep. Measures c. 120m diameter, with internal area 1.12ha. Formerly noted by the Ordnance survey 1st edition 2500 map of 1888 as a circular hillfort of c. 120m diameter located on the promontory rather than true promontory fort, and corroborated by Hughes in 1926 who noted that it had been almost obliterated then. However, no circuit now visible with repeated ploughing over years. Traces of curving bank to 2m high externally just visible from the edge of steep natural on NE. On SE bank,with outer ditch, followed by an outer bank and ditch to 0.5m high. Simple gap entrance midway along the main, inner bank. No sign of rampart on W side above steep natural slopes of Allt Fawr wood. It is possible that the site was more complex than present form suggests and that there were three lines of defence rather than two. In addition a small ditch across the interior may indicate an earlier enclosure, but not proven. Under improved pasture. On 1st Ed. OS map (1888). Minimal investigations, undated.

Enclosing Works

Traces of curving bank to 2m high externally visible from the edge of steep natural on NE. On SE bank with outer ditch followed by an outer bank and ditch to 0.5m high. No trace of defence on W side of above steep natural slopes of Allt Fawr wood. It is possible that the site was more complex than has been envisaged and that there were three lines of defence rather than two. In addition a small ditch across the interior may indicate an earlier enclosure, but not proven.
