Originally home to the O’Connor family in 1641, the fortified residence later passed to the Calcutt family by 1775. According to historical records from Carrigan in 1905, the structure fell into disrepair shortly after the Calcutts’ tenure, leaving behind the stone remnants visible today.

What remains of this once formidable dwelling includes portions of the west wall, stretching approximately nine metres, and the south wall, measuring roughly 8.2 metres in length and 1.7 metres in width. Both walls were constructed using rubble limestone, a common building material for defensive structures of this period. The ruins stand two storeys high, with evidence of an opening at the northwest corner; likely a doorway or window that once connected the tower’s interior spaces.

Archaeological evidence suggests the tower house may have been accompanied by a bawn, a defensive wall that would have enclosed a courtyard area to the west. These fortified enclosures were typical features of Irish tower houses, providing additional protection for livestock and serving as a first line of defence against raids. The combination of tower house and bawn represents the standard defensive architecture employed by landowning families in medieval and early modern Ireland, when such fortifications were essential for protecting both property and inhabitants.
