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 enclosure set located on the isolated summit of a north east to south west ridge above the floodplain of the River Tywi. The date or precise nature of the enclosure is unknown, but it is likely to be later prehistoric. It is defined by a single bank measuring between 3 and 4 meters high with traces of an accompanying ditch. A simple entrance at the south west corner is probably original.

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.
