Ross Castle

Ross Castle is a 15th-century fortress. A boat trip on nearby Lough Leane, the largest of the three lakes in Killarney, is a great way to explore the surrounding area.

Ross Castle is perched in a bay of Lough Leane. It is likely that Irish chief O'Donoghue Mór built it in the 15th century.
According to legend, O'Donoghue still slumbers beneath the waters of the lake. Every seven years, on the first morning of May, he mounts his magnificent white horse. If you manage to catch a glimpse of him, you will be lucky for the rest of your life.
Ross Castle was the last place in Munster to hold out against Cromwell. Its defenders, then led by Lord Muskerry, took heart from a prophecy that said the castle could only be taken by a ship. The Cromwellian commander, General Ludlow, knew of the prophecy and launched a large boat on the lake. When the defenders saw it, the surrender hastened—and the prophecy was fulfilled.Adults: €5.00
