Ross Castle stands on a rocky promontory on the shore of Lough Leane, the largest of the three Killarney lakes, within Killarney National Park. The tower house was built in the late 15th century by O'Donoghue Mór, chieftain of this part of Kerry, and represents the dominant architectural form of late medieval Gaelic Ireland — a tall defensive tower rising from a walled bawn (enclosure).
The castle has a particular historical significance as the last stronghold in Munster to surrender to Cromwellian forces — it held out until 1652, two years after most of the country. The prophecy that said Ross Castle would never be taken by land prompted the Cromwellian commander Ludlow to bring his artillery by boat across Lough Leane; the prophecy was technically fulfilled and the garrison promptly surrendered. The castle was restored by the OPW in the 1990s and furnished to represent a 16th-century tower house.
The location is as much the attraction as the castle itself. Lough Leane stretches north and east from the promontory; the Killarney mountains frame the western shore; the lower lake's wooded islands — Ross Island, Innisfallen (with its 7th-century monastery) — are accessible by rowing boat. The traditional Killarney jaunting car route runs from the castle gates.

What is the history of Ross Castle?
Ross Castle was built in the late 15th century by the O'Donoghue Ross clan as their stronghold on the shores of Lough Leane. It was the last Munster castle to hold out against Cromwellian forces — it finally surrendered in 1652. According to local legend, an ancient prophecy said the castle could never be taken by land, so Cromwell's forces floated cannon across the lake by barge to force the surrender.
