The monument comprises the remains of an earthwork/stone-built enclosure dating to the Iron Age period (c. 800 BC - AD 74, the Roman conquest of Wales).

The remains include a small roughly D-shaped enclosure measuring 51m by 52m and defined by a single bank 0.7m high. This was supported by an external ditch with low counterscarp bank.

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.
