This rectangular tower house stretches nearly 20 metres from east to west and rises through three storeys plus an attic level, its walls measuring an impressive 1.5 metres thick at the base. Dating from around the mid-17th century, as evidenced by the decorative draughting on its corbels and stonework, the castle represents a late example of Irish tower house construction during a particularly turbulent period in the country’s history.

The defensive nature of the structure is immediately apparent in its architectural features. The ground floor bristles with narrow slit openings, seven in total, distributed across three walls; most are square-headed and chamfered, with one distinctive round-headed example in the north wall. These defensive loops, now filled in, once allowed defenders to monitor and protect the approaches to the castle. The original entrance was centrally placed in the south wall, though a large broken opening in the north wall suggests a secondary entrance was added later, whilst the current entrance has been relocated to the centre of the east wall.

As the castle evolved from fortress to residence, later modifications reflect changing priorities and comfort levels. The upper floors show a fascinating blend of original defensive architecture and later domestic improvements; narrow slit openings with hood-mouldings sit alongside large rectangular windows that were clearly inserted in more peaceful times. The second floor provides access to the battlements through a round-headed doorway, leading to a defensive walkway that runs between substantial chimney stacks at each gable end. Corner bartizans at the western and eastern angles offered additional defensive positions, whilst the large blocked fireplaces at first and second floor levels in both gables speak to attempts at making this military structure more habitable. The floors themselves were supported by corbels projecting from the walls, a typical feature of Irish tower houses of this period.
