Summary

Small promontory fort lying on single promontory spur west of Porth Joke, at Inner Kelsey, seaward part of The Kelseys, headland SW of Newquay and E of Kelsey Head (Atlas No 3718). Sea cliffs to N, E, W. Irregular plan reflecting topography of cliffs, measuring c. 50m across enclosing 1.5ha. Rampart of earth and stone incorporates natural rock across neck of promontory, curving S and generally c. 6m wide and 0.8m-1.5m high outside, 0.3m-1.1m high inside, but very slight for c.7m from the cliff on E. Possible ditch. Original entrance possibly near centre of rampart, where it dips by c. 0.5m for some 3m. Interior falls towards cliffs with natural slope, broken by outcrops of bedrock, except inside the entrance where it forms a natural or modified platform c. 8m across and 0.8m high above the slope. Coastal grassland and site being eroded by sea. Minimal investigations recorded. Undated. On 1st Edition OS map (1885-1900).
