Ross Castle

Ross Castle

A 15th-century tower house on the shore of Lough Leane, seat of the O'Donoghue Mór clan before their dispossession in 1582.

History & details

Ross Castle was built by the O'Donoghue Mór family, who held this shore of Lough Leane until the Elizabethan confiscations of 1582 forced them out. Local legend says the last O'Donoghue Mór didn't die but sleeps beneath the lake, riding across the water on a white horse every May morning — anyone who sees him is promised good luck for the year. A granite sculpture near the park entrance on Mission Road depicts the legend, though some details on the panel — including the name 'Nelchra of Glena' inscribed there — haven't been traced to any documented source. A local prophecy also held that the castle would never fall until a warship sailed the lake; Cromwell's forces reportedly had a boat built and hauled overland to do exactly that in 1652.

The O'Donoghue Mór legend has been retold in several forms since it was first collected by Thomas Crofton Croker in 1825, and versions differ on small details, including which May morning the apparition appears. Local tradition also holds that the last O'Donoghue Mór was held on a small island near the castle, sometimes called O'Donoghue's Prison, before the clan's final dispossession. The story connects to nearby Innisfallen Abbey and to the Herbert and Kenmare estates, whose later ownership of the demesne shaped much of what visitors see in the National Park today, including the avenue leading to this castle. The granite sculpture at the park's Mission Road entrance — a relief panel beside an open-book lectern, attributed to sculptor L. Mangan — names 'Nelchra of Glena' as part of the story, a name not yet traced to any indexed historical source. It may survive only in oral tradition, or have been composed specifically for the sculpture.
