Castle History

Rising from the shores of Lough Leane, this imposing tower house is one of Ireland's most evocative medieval landmarks. Ross Castle's construction dates to the late 15th century, when it was built by O'Donoghue Mór, a powerful chieftain of the region. The castle served as a stronghold for the O'Donoghue clan, who controlled much of the surrounding lands. Defensive features such as thick walls, narrow windows, and corner towers made it well suited for warfare. Located within what is now Killarney National Park, the site was strategically placed to command lake and land routes. During the 17th century, the castle became involved in the Irish Confederate Wars. It was famously one of the last Irish strongholds to surrender to Cromwellian forces in 1652. Legend holds that the castle could only be taken once ships were brought onto the lake. After its surrender, the structure fell into gradual decline. Centuries of exposure left it a romantic ruin by the 18th century. Restoration work in the 20th century stabilized the surviving tower and walls. Today, visitors can explore the interior and climb its winding staircases. Boat tours on the lake often frame the castle against dramatic mountain scenery. Ross Castle endures as a powerful symbol of resistance, legend, and Ireland's medieval past.
