Known locally by the evocative names ‘Cloch na Cor-Rátha’ (Cloghnacoraha) or ‘Carey’s Rock’, this L-shaped structure offers commanding views across the surrounding landscape from its position on the northern end of a ridge. The three-storey house, measuring roughly 10 metres square, features a distinctive solar tower projecting from its southwest corner; a private chamber that would have served as the lord’s personal quarters. Built from roughly coursed limestone rubble with walls over a metre thick, the structure shows the characteristic slight base-batter typical of defensive architecture from this period.

The building’s interior reveals a surprisingly simple layout, with the ground floor appearing to consist of a single large chamber accessed through a round-arched doorway in the eastern wall. Wooden floors once divided the structure into its three levels, supported by joists that rested on stone offsets still visible in the walls. Whilst the eastern wall stands to its full three-storey height, time has been less kind to other sections; the north and south walls survive to two storeys, whilst the western wall rises only 2.5 metres. The attached solar tower, which would have been accessed from within the main house, now survives only to first-floor level. A defensive bawn wall once enclosed the area to the south, creating a fortified compound typical of Irish tower houses and fortified dwellings of this era.

Despite its imposing presence, historical records remain curiously silent about this structure. The Civil Survey of 1654-6 makes no mention of a castle here, noting only that Pierce Butler of Callan, County Kilkenny, held these lands in 1640. Today, the ruins share their hilltop with more recent additions; a quarry and farmyard immediately to the northwest, concrete walls built against the southern face, and a silage pit carved into the western slope of the ridge, all testament to the site’s continued agricultural use through the centuries.
