Summary

Small coastal promontory fort located on rugged W-facing promontory Langness peninsula to SE of island and overlooking St Michael's Isle to NE and Derby Haven to NW. Low rocky cliffs to the sea on N, E and S. Site surrounded by sea at high tide till 1950's. Defined by single bank and ditch on N, E and SW sides. Gaps on S and NW may be sites of possible entrances, but not defined. Geophysical survey c. 2000 identified 13 possible hearths and small excavation revealed pit with charcoal-rich fills of C14 dates AD 878-1017, together with stones (Doonan et al 2001). Rough coastal grassland and bare rock. Generally what remains well-preserved. On 1st Ed. OS map (1869).
