The O’Connor family occupied this fortified house in 1641, a particularly turbulent year that saw the outbreak of the Irish Rebellion. By 1775, ownership had passed to the Calcutt family, though their tenure proved to be the castle’s final chapter as a functioning residence. Shortly after the Calcutts took possession, the structure fell into ruin, leaving behind only fragments of what was once a substantial defensive dwelling.

Today, visitors to the site will find the skeletal remains of the castle’s south and west walls, both standing two storeys high despite centuries of decay. Built from rubble limestone, these surviving sections offer tangible evidence of the building’s original scale; the south wall stretches approximately 8.2 metres in length with a width of 1.7 metres, whilst the west wall extends for about 9 metres. A fragment of an opening, likely a window or doorway, can still be identified at the northwest corner of the ruins.

Archaeological evidence suggests the castle may have been more extensively fortified than these remains alone indicate. To the west of the main structure, there are possible traces of a bawn, a defensive wall that would have enclosed a courtyard area around the castle. This feature, catalogued separately as LA010-006003, would have provided an additional layer of security for the castle’s inhabitants during the uncertain times of 17th and 18th century Ireland. The site was documented in Carrigan’s 1905 historical work and later included in the Archaeological Inventory of County Laois, published in 1995.
