Cadw's description

The following provides a general description of the Scheduled Monument.

The monument comprises the remains of an earthwork/stone-built enclosure. The date or precise nature of the enclosure is unknown, but it is likely to be later prehistoric or medieval. The site covers an area of approximately 0.5 acres and is situated on a densely heather-clad summit, which is naturally defended by steep slopes on the west and southwest and with an enclosing bank on the east and southeast. A later rectangular sheepfold lies in the NE corner of the enclosure.

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, 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.
