Cloughoughter Castle, Medieval castle ruin on an island in Lough Oughter, County Cavan, Ireland.
The circular stone structure rises three stories high with walls reaching 15 feet in thickness on a small island within Lough Oughter's waters.
Built in 1233 by the de Lacy family, the castle served as a strategic fortress and prison before falling to Commonwealth forces in 1653.
The castle played a central role in the power dynamics between Irish clans, particularly the O'Reilly and O'Rourke families throughout medieval times.
Access to the castle requires a boat journey from the mainland, with guided tours available through local operators during favorable weather conditions.
The castle's circular design differs from traditional square Irish fortifications, making it an exceptional example of medieval lake castle architecture.
