Today, no visible traces remain of this stronghold; its stones were reportedly taken in the early 19th century to construct the nearby Kilbarry House. Local tradition maintains that the castle’s dismantling provided ready building materials for the new house, a common practice during Ireland’s period of architectural transformation.

Historical records suggest this O’Leary castle was a relatively late addition to Cork’s medieval landscape. According to research by O’Murchadha, documentary sources indicate the castle wasn’t built before the 1570s, placing its construction during a turbulent period of Irish history when Gaelic lords were consolidating their power in response to increasing English influence. The O’Learys, like many Irish clans of the time, would have built such fortifications to protect their territories and assert their authority over the surrounding lands.

The site represents a fascinating example of how Ireland’s built heritage has been recycled through the centuries. Whilst the castle itself has vanished from the landscape, its story survives through local memory and historical documentation, offering insights into both the medieval Gaelic lordships of Cork and the practical realities of 19th century construction, when ancient stones found new life in Georgian country houses.
