This rectangular earthwork measures 31 metres from northwest to southeast and 27.7 metres from northeast to southwest, defined by an earthen bank that rises 1.7 metres on its interior side. The site's defensive character is enhanced by an external fosse, or ditch, reaching depths of 1.3 metres, with a low counterscarp bank no more than 0.4 metres high running along the southeastern and northwestern sides.

The northern corner features a break in the earthwork approximately 5 metres wide, complete with a causeway that would have served as the original entrance to the enclosure. This gap in the defences suggests a controlled access point, typical of medieval moated sites which often served as fortified farmsteads or minor manorial centres during the Anglo-Norman period in Ireland.

Today, the interior of the site slopes gently down towards the northwest and bears the faint traces of cultivation ridges, evidence of later agricultural use that overlaid the medieval occupation. These ridges, known locally as lazy beds, indicate that long after the site's abandonment as a defensive structure, the fertile ground within the old earthworks continued to be worked by local farmers, adding another layer to this palimpsest of Irish rural history.
