A promontory separated from the mainland by a deep chasm which makes the site nearly inaccessible. A grassed-over bank 0.5 m high runs along the landward side of the promontory, turning at the E end to run for a further 10 m along the cliff edge. Possible hut sites occupy the interior.
An Antoninianus of the late 3rd C AD and two Romano-British bronze ox-head bucket-handle mounts, also probably of 3rd C date, were found as the result of the use of a metal detector in March 1977.
The monument is of national importance for its potential to enhance our knowledge of Romano British/Prehistoric settlement and defence. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. The structures themselves may be expected to contain archaeological information concerning chronology and building techniques.
The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
