Summary

Small coastal promontory fort located NW-facing promontory to NE of Dalby Point on W coast of island. Along coast to NE of Borrane Creglea (Atlas No 4201). Uninterupted views up and down coast. Steep slopes fall to sea on N and W and steep-sided stream course on SW, give natural definition on these sides, with vestiges of rampart cutting off promontory and fields beyond on E. Interior measures c.26.5m E-W by 17.5m N-S, with estimated area 0.05ha. The site is higher than its surrounds and along E edge, and above drop to an outer ditch, is a very low and nearly imperceptible curving bank with a possible, very shallow, internal ditch. Outer ditch, formerly c. 4m wide and to 0.5m deep, but now incorporated in, and nearly destroyed by, modern boundary wall. Possible entrance where curving bank meets steep slopes on N, but very eroded and conjecture. Hollows in interior towards W end may be sites of structures. No evidence for suggested Viking longhouse. Rough grass cover and gorse. On 1st Ed. OS map (1869). Minimal investigations, undated.
