Visitors approach the site via a causeway from the southeast, a narrow earthen path roughly 30 metres long and 4 metres wide that rises nearly a metre above the surrounding wetlands. This elevated position would have offered the castle’s defenders clear views across the landscape whilst making any assault on the fortification considerably more difficult.

The castle’s most prominent feature is its rectangular bawn wall, measuring 20 metres north to south and 26 metres east to west, which once enclosed the main defensive courtyard. At the southwest corner, fragmentary ruins of a tower still stand, whilst the eastern wall contains a gateway positioned near its southern end, strategically placed to overlook the approaching causeway. Though much of the original structure has been lost to time, the surviving elements reveal thoughtful defensive planning; the gateway is flanked by gun loops on either side, narrow openings that would have allowed defenders to fire upon attackers whilst remaining protected behind the walls.

Archaeological surveys note that only the southern side of the gateway opening remains intact today, with the ground dipping sharply towards the entrance, possibly indicating where a defensive ditch or similar feature once existed. Whilst portions of the bawn wall have undergone repairs and reconstruction in recent years, no other defensive features are immediately apparent along its length. The site was documented by the Archaeological Survey Unit at UCC, with subsequent revisions by Patrick F. O’Donovan and Paul Walsh, forming part of Ireland’s extensive catalogue of medieval and early modern fortifications.
