The rectangular tower, measuring 14 metres north to south and 11 metres east to west, rises to four storeys, though it originally stood taller. Heavily overgrown fragmentary remains of a 17th-century range can be found on the north side. The tower’s ground floor is accessed through a pointed arch doorway in the north wall, with the chamber lit by central window openings in the east, south, and west walls. A fascinating architectural detail reveals itself in the complex internal arrangement: directly above the ground floor entrance, another doorway at first floor level leads through a lobby to the main chamber and connects to a spiral staircase in the northwest corner.

The tower’s defensive and domestic features become more apparent as you ascend. The first floor chamber, lit by a central window in the south wall, is covered by a rounded wicker-centred vault running north to south. The second floor, accessed from the stairwell through a door in the northeast corner, contains several notable features including a garderobe chamber in the north wall covered by a segmental vault, complete with a murder hole in the floor positioned above the first floor doorway; a clear reminder of the castle’s defensive purpose. An inserted fireplace in the southwest corner suggests later modifications for comfort. Though little remains of the third floor walls, the inward inclination of the east and west walls indicates it was once covered by another vault.

The annex range abutting the tower on the north side survives only partially, with just the east wall and northwest corner still standing, both heavily covered in ivy. Visible fireplaces on the east wall feed into a tall rectangular chimney stack, whilst gun loops pierce the walls, giving the structure an early 17th-century appearance. In the farmyard to the south, an inscribed arch stone has been preserved bearing the inscription ‘I.E.G. 1579’, the initials of John Fitz-Edmond Fitzgerald, who likely renovated the existing structure at that time. The high enclosing walls on the west side appear to be later additions from the 18th or 19th century, probably associated with Cahermone House, which once stood a short distance to the southeast but has since been demolished.
