This flat-topped earthwork mound measures roughly 33 metres across at its base and rises between 6.4 and 7.4 metres high, with an oval summit spanning about 10 metres in diameter. The summit is enclosed by a low stone wall, now only two courses high and partially hidden by grass, whilst a solitary beech tree grows at the top. The motte’s sides drop away steeply on all but the northern face, where the slope is more gradual.

The strategic importance of this location becomes clear when you consider its surroundings. Just 25 metres to the north-northwest sit the remains of Rathcool Castle and what appears to be a 17th-century house, whilst Rathcool church and graveyard lie 350 metres to the south. Historical records suggest this was once a significant administrative centre; in 1297, Walter le Bret, the sheriff of Tipperary, was reportedly robbed of £100 from his manor here, a substantial sum for the time.

Whilst no visible evidence of a bailey remains today, the flat ground to both the north and south could have served this purpose. The northern area has since been transformed into landscaped gardens surrounding the castle and house, whilst archaeologist Lyons identified the southern area as another likely candidate for the bailey’s original location. A ridge running north to south on the eastern side of the motte would have provided additional natural defence, making this an ideal spot for Norman settlers to establish their authority over the surrounding countryside.
