This ruined rectangular stone structure, which once measured roughly 16 by 7 metres, appears on the 1837 Ordnance Survey map as an intact building, but by the 1913 revision, only fragments of the northwest wall remained standing. The castle sits 130 metres south of a Norman motte and bailey earthwork, suggesting this area held strategic importance for centuries. Interestingly, no castle appears at this location on the 1657 Down Survey maps, leaving questions about its exact construction date.

Today, visitors will find only modest traces of the original limestone walls, which stand less than a metre high in their best preserved sections. The eastern wall shows the most substantial remains, complete with what might be an original door jamb at its southern end and a rough buttress added for support. The walls were built using undressed limestone blocks laid in fairly regular courses with a rubble core, all bonded with mortar; a typical construction method for minor fortified houses in medieval Ireland. Corner buttresses at the north and south angles, along with some modern repairs and repointing, hint at various attempts to preserve the structure over time.

The castle’s association with the Nugent family, as noted on the Ordnance Survey maps, connects it to one of the Anglo-Norman families who settled in Westmeath following the 12th-century invasion. While the ruins may not impress at first glance, they represent the type of smaller fortified residence that once dotted the Irish landscape; practical defensive homes for minor gentry rather than grand statements of power. The site now appears as an irregular patch of trees when viewed from above, with some earthworks visible to the northwest that may represent additional structures or defensive features from the castle’s active period.
