The four-storey structure, built from coursed limestone rubble with distinctively rounded corners and a defensive base-batter, forms part of a broader medieval landscape that includes a church to the southeast and a ringfort to the northwest. Though the Civil Survey of 1654-6 recorded it as a ‘castle out of all repaire’, the tower house has survived remarkably well into the present day, its substantial walls testament to the quality of its original construction.

The castle’s defensive features reveal much about its turbulent past under the ownership of Theobald Purcell of Loughmoe, who held the property in 1640. The main entrance, positioned centrally in the eastern wall, consists of a two-centred doorway with rebated jambs; originally protected by a machicolation at wall-walk level, though this upper defence has since been lost. While access to the interior is currently restricted by a locked gate, the exterior alone demonstrates the careful planning that went into its construction, from the strategic placement on high ground to the architectural details designed to repel attackers.

Archaeological evidence suggests the tower house once stood within a larger defensive complex. Ordnance Survey letters from the 19th century describe a circular enclosure surrounding the castle, which today can only be traced through variations in vegetation growth. This feature likely represents the remains of an earth and stone bawn, a fortified courtyard that would have provided additional protection and space for domestic buildings, livestock, and storage. Together, these elements paint a picture of a significant medieval stronghold that played an important role in the local power structures of North Tipperary.
