Built by the O'Donoghue Mór clan on the shores of Lough Leane in Killarney National Park, Ross Castle was among the last strongholds in Ireland to fall to Cromwell's forces, only captured after artillery was floated up the River Laune by boat. It is a classic example of a chieftain's tower house in a lakeside setting.
