The main feature is an impressive earthen mound, roughly circular in shape, with a flattened summit measuring approximately 24 metres northwest to southeast and 17 metres northeast to southwest. The mound rises between 6 and 7.5 metres high, its tree-covered slopes expanding to a base roughly 45 metres across. Around this central motte runs a defensive ditch, or fosse, between 8 and 12 metres wide and reaching depths of 2 to 3 metres, with an additional outer bank particularly prominent on the northern side.

The castle’s bailey, a crescent-shaped enclosure where daily activities would have taken place, extends from the western side of the motte. This grass-covered area spans about 40 metres by 27 metres and is defined by scrub-covered scarps that still stand around 1.5 metres high in places. This secondary defensive space would have housed workshops, stables, and other essential structures needed to support the wooden tower that likely crowned the motte during its active use.

The strategic placement on the esker ridge, which extends both west and east-southeast, would have provided the Norman lords who built this fortification with commanding views across the surrounding landscape. Today, whilst the wooden structures have long since vanished, the earthworks remain remarkably well-preserved, offering visitors a tangible connection to the medieval period when these castles served as both military strongholds and administrative centres throughout the Irish midlands.
