The four-storey rectangular tower house, measuring approximately 7.4 metres east to west and 6.3 metres north to south, once formed part of a substantial estate that included 312 acres, two other ruined castles, a hall, a quarry, and several cottages according to the Civil Survey of 1654-6. The property belonged to Edward Scurlock of Frane, who also held significant lands in nearby Drissoge and Dirlangan, totalling over 750 acres in Athboy parish.

Today, much of the castle’s southern portion has crumbled away, leaving the ivy-covered north wall as the most intact element of the structure. The ground floor retains its east-west barrel vault, with only a small light in the south wall and breaks in the north and west walls remaining as notable features. The first floor reveals more of the castle’s former domestic arrangements; a garderobe occupies the northwest corner, whilst the centre of the north wall houses a fireplace, and a window with stone seats graces the eastern end. Similar patterns repeat on the upper floors, though the second floor lacks a fireplace and the third floor shows only remnants of window embrasures where the parapet once stood.

Archaeological evidence suggests the tower house wasn’t isolated but formed part of a larger defensive complex. Just five metres east of the main structure, wall footings outline another building measuring nearly 22 metres long. From here, a series of scarps, banks, and ditches trace what may have been the original bawn walls, enclosing the castle and its immediate grounds. These earthworks extend eastward before turning north and west, eventually meeting a north-south road bank. Beyond these defensive features, additional field systems cover approximately nine acres, hinting at the agricultural wealth that once sustained this fortified residence.
