This nearly square tower, measuring roughly 9.2 by 9 metres, rises at least three storeys despite centuries of neglect and decay. Local tradition attributes its construction to the O’Mullallys or Lallys, prominent families who once controlled this corner of North Galway, though the exact date of its building remains uncertain.

The castle’s current state tells a story of both resilience and ruin. A prominent crack splits the centre of the north wall, whilst a collapsed section of the eastern wall has inadvertently revealed the spiral stairwell tucked into the northeast corner. Despite this deterioration, several architectural features remain visible to keen observers: a broken garderobe chute emerges at the base of the north wall, evidence of the castle’s medieval plumbing, whilst a fireplace on the second floor of the west wall hints at the comfort once enjoyed by its inhabitants. The surviving windows, each a single light opening, display a variety of decorative heads; some circular, others rectangular, and a few featuring the distinctive ogee arch popular in later medieval Irish architecture.

The castle doesn’t stand entirely alone in its marshy domain. Later structures, likely farm buildings or cottages from more recent centuries, lean against the south wall, whilst mysterious earthworks to the west suggest the tower may once have been part of a larger defensive complex. These faint traces in the landscape hint at a more extensive settlement, now largely reclaimed by the boggy pastureland that characterises this part of Galway.
