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 medieval. The monument forms a rectangular enclosure, about 100m north-east to south-west by 70m, set on the summit of a natural hillock, above the flood plain of the Afon Vyrnwy: the north-west and north-east sides rest on steep slopes, the enclosure being defined elsewhere by a double bank with a medial ditch. The monument is thought to have been the caput (centre) of the manor of Dynas, mentioned in the 14th century. 'Tooled stonework' has been noted within 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.
