This four-storey limestone structure, built from roughly coursed rubble, was already in ruins by the time of the Civil Survey in 1654-6, which described it as having “the walls onely standing neer the vaulted chappell being all wast”. The castle belonged to Daniell Hogan of Graige in 1640, though its origins likely stretch back much further into the medieval period.

The tower house reveals its architectural sophistication through several surviving features. Entry was through the eastern wall, where visitors would descend steps into the interior before encountering spiral stairs in the southeast corner. The ground floor retains its pointed vault ceiling, still showing impressions from the wicker centring used during its construction. A dividing wall on this level may represent later modifications to the space. The first floor once boasted an oriel window projecting from the south wall, though only a chamfered jamb survives today, whilst the third floor preserves a particularly fine cusped ogee-headed window with plain spandrels and chamfered exterior detailing.

Perhaps the most intriguing element is the bartizan, a small turret, at third-floor level near the southwest angle. Supported by four corbels, the southern corbel on the west wall features a carved human head on its underside; a small but remarkable detail that connects us directly to the medieval craftsmen who built this stronghold. The structure has suffered significant damage over the centuries, with the north wall completely destroyed and the northern end of the west wall collapsed, yet what remains provides valuable insights into the design and construction of Irish tower houses. External buttressing, evidenced by wall remains projecting from the southwest angle, would have provided additional structural support to this once-imposing defensive residence.
