This distinctive fortress once belonged to the Archbishop of Armagh, according to the Civil Survey of 1654-6, which noted the presence of ‘one castle and some cottages’ on the church lands at that time.

The castle’s eastern doorway opens into a ground floor chamber measuring roughly 5.8 metres east to west and 4.9 metres north to south, topped by a barrel vault running the same direction. The space is spartan but functional, lit by double-splay windows in both the eastern and western walls. A passage in the east wall connects to a spiral staircase tucked within the northeastern tower, allowing access to the upper levels.

Today, only fragments of the first floor remain; the western wall still shows a large window opening, whilst the southwestern tower preserves evidence of another spiral staircase that once climbed to the second floor. The corbelling at the top of this tower suggests the castle rose no higher than this, making it a relatively modest fortification. The structure has been under a preservation order since 1945, ensuring this piece of medieval Irish architecture remains protected for future generations to explore and study.
