Now designated as National Monument 365, the castle showcases the typical defensive architecture of medieval Ireland, complete with murder holes, spiral staircases, and the remnants of what was once a formidable fortress.

The tower house measures roughly 9.5 by 8.25 metres and displays some fascinating architectural quirks. Its interior is cleverly divided into two sections; the western part contains three floors of spacious rooms, whilst the eastern portion squeezes in five floors of smaller chambers, most accessed directly from the spiral stairwell tucked into the southeast corner. The main entrance, a pointed arch doorway slightly off-centre in the east wall, leads to a lobby overlooked by a murder hole, beyond which lie a guardroom, the stairway, and the main ground floor chamber. The building retains many original features including ogee-headed windows, though various alterations over the centuries have left their mark, particularly the multiple fireplaces inserted at different periods, some blocking original windows and alcoves.

Though time has taken its toll on the upper portions of the castle, with only fragments of the parapets and attic gables surviving, enough remains to paint a picture of its former glory. The tower once stood in the northwest corner of a small square bawn, with stables and outbuildings to the northwest, though these have long since disappeared. A building that adjoined the castle's north side, still visible on 1922 Ordnance Survey maps, now exists only as a faint shadow line on the wall. The surviving architectural details, from the garderobe chute visible on the north wall to the corbels that once supported a machicolation above the east entrance, offer tangible connections to the lives of those who built, defended, and inhabited this sturdy fortress over its four and a half centuries of existence.
