This tower house dates back to around 1450, built during a turbulent period of Irish history when such fortified residences were essential for survival. The castle takes its name from Torlough O’Brien, though historical records suggest it was actually constructed by his son, Murrough O’Brien, who needed a stronghold to control this strategic location overlooking the lake.

The castle’s architecture tells the story of medieval Irish defensive design; thick limestone walls, narrow windows, and a commanding position that offered both protection and surveillance over the surrounding countryside. For centuries, it served as the seat of the O’Brien clan in this part of Clare, witnessing countless conflicts, alliances, and the gradual transformation of Gaelic Ireland. The tower house design was particularly popular among Irish nobility during the 15th and 16th centuries, offering a practical solution that combined residential comfort with military necessity.

Today, the castle stands as a romantic ruin, its weathered stones slowly being reclaimed by ivy and time. Visitors can still make out the remains of its barrel vaulted ceilings, the spiral staircase that once connected its multiple floors, and the murder hole above the entrance; a grim reminder of the castle’s defensive purpose. The setting beside Lough Inchiquin adds to its appeal, with the lake’s waters reflecting the ancient walls and creating a scene that has captivated artists and photographers for generations.
