The castle once measured approximately 13.64 metres on each side and featured four circular corner towers; a compact but formidable design typical of Irish tower houses. Today, only fragments of the original structure survive, with parts of the tower and walls still visible amongst the gardens that now occupy the site.

The most substantial surviving element was the southwest corner tower, which in 1838 still rose to an impressive height of 7.44 metres. This cylindrical tower, with its thick walls measuring 0.85 metres and an internal diameter of just 1.38 metres, would have provided both defensive capabilities and living quarters for the castle’s inhabitants. The main tower house itself stretched about 13.4 metres in length, forming the heart of this fortified residence. These precise measurements, recorded in the OS Letters by O’Flanagan in 1928, offer a rare glimpse into the castle’s original proportions and help us imagine how it once dominated this corner of the moated enclosure.

The site’s historical significance has been recognised through a preservation order issued in 1940 under the National Monuments Acts, ensuring that these medieval remnants are protected for future generations. Though much reduced from its former glory, the castle ruins continue to tell the story of medieval Wicklow, when such fortified structures dotted the landscape, serving as both homes and strongholds for the local nobility.
