The motte itself is a substantial circular mound with a flat top, rising about 6 metres high with a base diameter of roughly 46 metres, whilst the summit spans approximately 12 metres across. A defensive bank, measuring about 3.5 metres wide and 0.7 metres high, encircles the summit, providing an additional layer of fortification for whoever commanded this strategic position.

The southern and western approaches to the motte are protected by a flat-bottomed fosse, or defensive ditch, measuring around 7 metres wide and 2 metres deep. An external bank runs along the south and southwest sides, standing about 1 metre high on the inner side and 0.6 metres on the outer, creating yet another obstacle for potential attackers. These earthworks separate the motte from its accompanying bailey, an irregularly shaped enclosure measuring approximately 62 metres from east to west and 30 metres from north to south.

Within the southwest quadrant of the bailey, archaeological records indicate the presence of a castle site, suggesting this was where the main residential and administrative buildings once stood. This type of fortification, introduced to Ireland by the Anglo-Normans in the late 12th century, represents a crucial period in Irish history when new military technologies and architectural styles fundamentally changed the landscape of power and control across the island.
