The fortification sits on an elevated position roughly 80 metres east to west and 60 metres north to south, accessible only by a narrow causeway from the southeast that stretches about 30 metres long and 4 metres wide. This strategic placement, typical of Irish tower houses, would have made the castle easily defensible whilst providing commanding views across the surrounding wetlands.

The castle complex consists of a rectangular bawn, or fortified enclosure, measuring 20 by 26 metres, with the fragmentary remains of a tower at its southwest corner. The tower’s surviving walls, built from uncoursed limestone blocks bound with lime mortar, stand two storeys high on the north and east sides. These walls reveal fascinating defensive features including gun loops, a spiral staircase lit by slit windows in the northwest corner, and evidence of timber floors between levels shown by joist holes in the masonry. The bawn’s gateway, positioned near the southern end of the eastern wall to overlook the causeway approach, is flanked by gun loops on either side; a practical arrangement that would have allowed defenders to cover anyone attempting to cross the exposed causeway.

Historical records suggest this was the castle captured by O’Donnell in 1516, as mentioned in O’Rorke’s historical accounts from 1889. The castle’s current ruinous state owes much to the march of progress; according to local memory, significant quantities of stone were removed in the late 19th century to construct the nearby Sligo, Leitrim and Northern Counties railway line, now itself defunct. What remains offers a glimpse into the turbulent world of Gaelic lordships, where fortified residences like this served as both homes and strongholds, their thick walls and narrow windows designed to withstand siege whilst their elevated positions allowed control over the surrounding landscape.
