The building, which overlooks a church to the south, survives only to first-floor level and presents a rather austere appearance with its roughly coursed sandstone rubble walls that have an almost cyclopean quality. Despite the heavy covering of ivy that obscures much of the structure, enough detail remains to piece together the layout of this modest fortification.

The rectangular building contains a narrow ground-floor chamber measuring roughly 6.65 metres north to south and 3.05 metres east to west, with walls an impressive 2 metres thick. Entry is through a segmental-arched doorway centred in the eastern wall, though this appears to be a later insertion rather than an original feature. The ground floor once had a wooden ceiling supported within the thickness of the walls, and a flat-headed window in the western wall replaced an earlier opening. At first-floor level, a single round-arched window survives in the northern wall, now largely hidden by ivy growth, whilst the remnants of a garderobe chute can be seen at the eastern end of the southern wall. Stone stairs at the same end likely provided access to an eastern chamber that has since been destroyed.

The castle’s construction is notably rustic, with no cut stone used anywhere in the fabric of the building. It remains unclear whether what survives represents the entire original structure or merely its western half, though there is some evidence for a bawn wall extending eastward from the southeast corner. Archaeological testing carried out in 2001 on a nearby proposed house site found no additional features, suggesting the castle may have stood relatively isolated on its commanding position above the ravine. The site was documented in detail by Jean Farrelly and Caimin O’Brien in their Archaeological Inventory of County Tipperary, providing valuable insights into this modest but intriguing example of medieval Irish fortification.
