Cadw's description
Summary description and reason for designation
The following provides a general description of the Scheduled Ancient 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 enclosure is univallate, roughly circular in plan, measuring 70m E/W by 75m N/S, and bounded by a slight bank and a deep ditch with a counterscarp. The entrance is on the eastern side of the monument. A linear bank and ditch, extending 50m out from the entrance, is likely to be a more modern feature. It is likely that the enclosure represents an Iron Age hillfort with later additions.
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.
