Records show this fortification existed as early as 1574, when it belonged to one Melaghlin McDonell. The rectangular tower, measuring 13.3 metres long and 11.4 metres wide, remains well-preserved and has undergone partial restoration, offering visitors a tangible connection to medieval defensive architecture.

The tower’s defensive features reveal the turbulent times in which it was built. The main entrance, a pointed arch doorway on the eastern wall’s northern end, is now secured with an iron grill but once served as the first line of defence, complete with a gun loop to the south and a murder hole overhead in the entrance lobby. The interior layout is surprisingly complex, with an intramural staircase leading from the ground floor to the first floor, where a spiral staircase in the southeast corner continues up to the third floor. Another spiral staircase in the southwest corner then provides access to the roof. The second and fourth floors each contain a main chamber with a subsidiary room to the south, whilst various floors feature fireplaces, mural passages, and garderobes; essential amenities for medieval living.

Archaeological evidence suggests the tower once stood within a larger defensive complex. Three circular towers, each approximately six metres in diameter, survive to the north, east, and south of the main structure, likely marking the original bawn wall’s perimeter, though this is now hidden beneath a later orchard wall. These circular towers have since been repurposed as storage buildings. Various architectural details, including windows ranging from simple slits to ogee-headed single lights and rectangular multi-light openings with hood mouldings, showcase different periods of construction and modification. A later pointed arch doorway inserted into the western wall, along with a blocked doorway above it, hints at a now-vanished structure that once abutted the tower, demonstrating how the castle evolved over its long history.
