An oval enclosure, c.62m by 52m, defined by scarps and the denuded remnants of a bank, with an additional bank on the NW-E. The outer circuit appears to extend to the S, defining a further enclosure, c.50m across. (Coflein–defended enclosure of unknown date)

While the description from this OS card written in 1912, and a further description written in 1957 both claim this is not defensive in nature, a site visit in 2006 in the context of considering prehistoric defended enclosures, determined that this was in fact of a defensive nature and in both scale and position matched many other such enclosures which survive in various forms within the Gwent landscape. The enclosure is situated on a small promontory just below the summit of a hilltop, with a steep slope to the south, and slightly less steep slopes to the east and west, the location commands good views in all directions, except to the north which is taken up almost solely by the view of the nearby Skirrid Fawr mountain and hillfort. The earthworks are difficult to closely define as they have been much spread from ploughing in the past. However a rough estimate (using a tape measure - but with subjective interpretation of beginning and end of slopes etc.) gives the width of the ditch, crest to trough as 11m, with a further width of 7m from the trough to the crest of the counterscarp bank. Heights could not be determined as the traces were too ephemeral. The interior diameter of the site is approximately 55m. The first edition OS mapping of this site suggests a possible bivallate nature to the northern part of the earthwork, but it is felt that this in fact represents the counterscarp bank, and a modern close contour survey of the site, would give a much more accurate presentation of the facts. Similarly the earlier suggestion of a southwest entrance has been ignored as it was felt this cannot be accepted even as a 'possible' from the current state of the monument

Gatehouse Comments

Marked intrenchment on 1st edition OS map, nothing visible on aerial photo other than ploughed field. Medieval church 600m away but nothing in the map features to suggest this as a medieval centre, although it is close to the road. It is difficult to see the reason for the Glamorgan-Gwent Archaeological Trust HER identification of this as a medieval ringwork although this is a possibly, if doubtful, identification.
