This moated site forms an unusual rectangular enclosure, measuring approximately 52 metres north to south and 31 metres east to west. What makes it particularly intriguing is its quirky geometry; whilst three of its corners meet at neat right angles, the eastern section curves gracefully from east to southwest, giving the site an distinctive asymmetrical character.

The defensive architecture consists of three concentric elements that would have provided formidable protection in medieval times. At its heart, a broad internal earthen bank rises up to 80 centimetres on the inside and an imposing 1.15 metres on its outer face, with a width spanning over five metres at its base. Beyond this lies a wide, flat-bottomed fosse, or defensive ditch, measuring 3.5 metres across and plunging nearly a metre deep. A third line of defence comes in the form of an external bank, though time has been less kind to this outer rampart; it remains well-preserved along the eastern and southwestern sections but has eroded considerably to the north.

The site’s original entrance reveals careful medieval planning, positioned strategically on the western side where two six-metre gaps in the banks align with a causeway crossing the fosse. The southwestern and northwestern corners were cleverly constructed at acute angles to create a funnel-like approach that would have made any unwelcome visitors think twice. An annexe structure once abutted the external bank on the southeastern side, suggesting this wasn’t merely a defensive site but part of a larger medieval complex. Though centuries of Irish weather and agricultural use have softened its once-sharp edges, the earthwork remains remarkably legible in the landscape, its banks and ditches still clearly defining the rectangular footprint of what was once a significant medieval stronghold.
