Prehistoric  

The following provides a general description of the Scheduled Ancient Monument. The monument comprises the remains of a defended enclosure, which probably dates to the Iron Age period (c. 800 BC - AD 43). The enclosure is located on a narrow coastal promontory above the sea, high cliffs form apart of the defensive circuit on three sides whilst the narrowest part of the promontory is defended by an outer rock-cut ditch about 4m wide, 2m deep and 50m long, on the inner side of which are two banks of earth and stone about 1m high. The internal defended area measures about 200m east to west and 100m north to south. The location of the entrance may be a simple gap towards the south end of the defences. A single circular terrace, probably a house site has been noted in the interior. The monument is of national importance for its potential to enhance our knowledge of later prehistoric defensive organisation and settlement. The site forms an important element within the wider later prehistoric context and within the surrounding landscape. The site is well preserved and retains considerable archaeological potential. There is a strong probability of the presence of evidence relating to chronology, layout, building techniques and functional detail. The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
