Coolcroo Castle, Coolcroo, Co. Tipperary North
Though time has not been kind to this structure, what remains tells the story of a possible T-plan tower house that once stood as a formidable residence and stronghold. The northern section, which survives to first-floor level, reveals walls built from roughly coursed limestone rubble with a distinctive sloping base, a feature designed to deflect projectiles and make scaling the walls more difficult.
The castle’s ground floor contains a barrel-vaulted chamber running east to west, complete with defensive features that speak to turbulent times. A small recess in the north wall houses both a narrow window opening and a gun loop, whilst above this, cleverly concealed at mezzanine level, lies a secret chamber. This hidden room could only be accessed from the first-floor chamber in the north tower, suggesting it may have served as a place to store valuables or perhaps as a last refuge during attacks. The ingenuity of medieval builders is evident in the mural stairs built into the eastern wall, which lead to a lobby in the northeast corner that provides access to both the main first-floor chamber and the smaller room in the north tower.
Perhaps the most intriguing survivor is a small tower projecting from the north wall, which still stands to second-floor level. This tower contains a garderobe, essentially a medieval toilet, with its outlet visible at the base of the north wall; a practical reminder that even in times of conflict, daily necessities had to be accommodated. From the north tower chamber, one could access not only this garderobe but also the upper tower chambers, creating a vertical circulation system that maximised both space and defensive capability within the castle’s compact footprint.
