The castle site occupies the northern quarter of what was once a well-defended rectangular enclosure, measuring roughly 67 metres northwest to southeast by 62 metres north-northeast to south-southwest. Though time has reduced the fortifications to earthworks, you can still trace the impressive defensive system: a substantial bank and fosse (defensive ditch) protected three sides, whilst a drain formed the southwestern boundary.

The interior of the enclosure tells its own story through subtle archaeological features; uneven ground marked by slight rises, low banks, and the faint footings of long-vanished walls. These fragments hint at the various buildings and structures that once filled this defended space, perhaps including domestic quarters, storage facilities, and workshops that supported castle life. A low rise to the north would have provided the castle’s occupants with clear views across the surrounding landscape, whilst the marshy ground to the southeast, south and west offered natural protection against potential attackers.

Beyond the main enclosure, the medieval landscape reveals itself through a network of banks and ditches that create a complex pattern of smaller enclosures, likely used for agricultural purposes or as additional defensive outworks. To the northeast, the remains of what appears to be a medieval road or sunken way can still be detected; a reminder of how this fortified site once connected to the wider world. Archaeological survey work by Alison McQueen, Vera Rahilly and Caimin O’Brien has helped document these features, preserving knowledge of this medieval stronghold for future generations.
