The site consists of an impressive flat-topped mound reaching nearly 9 metres in height, with a diameter of up to 36 metres at its base narrowing to about 20 metres at the summit. To the east-southeast lies the bailey, a defended courtyard measuring roughly 36 by 39 metres, created by scarping the natural terrain around its perimeter to form protective earthen walls between 1 and 3 metres high.

Historical records suggest the castle was once more elaborate than what remains today. Thomas Wright’s 1758 illustrations depict the site surrounded by a wide defensive ditch, or fosse, with an octagonal structure crowning the motte’s summit; features that have since vanished save for remnants of the fosse on the northwest side. The bailey’s exact boundaries have become increasingly difficult to trace over the centuries, though the scarped earthworks still hint at its original defensive purpose.

Like many motte and bailey castles built during the Anglo-Norman conquest of Ireland in the 12th and 13th centuries, this fortification would have served as both a military stronghold and administrative centre. The elevated motte provided an excellent vantage point over the surrounding countryside, whilst the bailey below would have housed garrison buildings, stables, and storage facilities essential for maintaining control over the local area. Today, these earthworks stand as a testament to the tumultuous period when Norman lords sought to establish their authority across the Irish landscape.
