Built sometime before the 17th century, this substantial fortification measures 54 feet long by 20 feet broad, with its walls remarkably intact right to the top. The tower features a mix of square windows and two Gothic arched openings that once served as defensive loop holes. Inside, visitors would have climbed using a combination of wooden ladders and the original spiral stone staircase, entering through a door on the west side near the northwest corner.

The castle formed part of a larger defensive complex that included a bawn, essentially a fortified courtyard wall, and a 17th century house. The house, now reduced to its foundations, once projected westward from the castle’s northwest angle for about 54 feet. The bawn wall, built from uncoursed rubble, extended along the platform’s edge above steep slopes, creating a formidable defensive position. Two circular gate towers marked the entrance to the complex, situated about 20 yards south of the main tower. The eastern tower still stands to a height of about 2.5 metres, whilst only the entrance remains of its western counterpart.

When the Ordnance Survey documented the site in 1838 to 1840, they noted more substantial remains of the gate towers; the eastern one measured 12 feet in diameter with walls 2 feet thick, though it had already suffered a 7 foot wide breach on its western side. The western tower retained about 10 to 12 feet of its structure, complete with a pointed arched doorway measuring 7 feet high and just 2 feet 6 inches wide. Today, the monument is protected under a preservation order dating from 1940, ensuring these remnants of Ireland’s turbulent past remain for future generations to explore and understand.
