Summary

This fort occupies a rocky promontory that rises into a broad hammerhead beyond the neck, where a single wall some 80m in length spans the outcrops on the seaward side; the wall measures about 2m in thickness over boulder faces and is up to 0.7m high. An entrance 1.9m wide lies towards the western end of the wall and is approached obliquely up the slope by a narrow track with a stone revetment along its lower side. The interior of the fort describes a shallow V on plan and, including an area beyond a deep crevice at the W end, measures 480m in total length from E to W by 110m transversely (4.6ha), tailing off into bare outcrops at its ends and along the seaward side. A target area within the MoD range, it has been devastated by bombs and shellfire, but the footings of three sub-rectangular huts survive within the interior, while a circular fourth 2.8m in internal diameter overlies the wall. Together with a fifth outside, these are probably all of more recent date.
