Description

A defended site with the sea on the N and W sides, a natural gully to the SE and a massive bank and ditch to the SW. The site has recently been excavated, and was shown to have comprised a level promontory defended by a bank, now surviving to a height of 2 m, inside a ditch 13 m wide and 4 m deep. The interior occupies some 250 sq. m, but some on the NW side has been lost through erosion of the cliff face. A large rectangular structure with rounded corners occupies the NW part of the interior.

The monument is of national importance for its potential to enhance our knowledge of 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.
