Ross Castle

Ross Castle is a 15th century castle build by O’Donoghue Mór on the shores of Lough Leane (Lower Lake). The castle is the centre piece of Ross Island with many trails branching off from it deep into the island, ducks to be fed by the lakeshore and boat trips around the lake available from just outside the castle.

There is a poem about the castle that stated the only way the castle could be taken was when a warship could sail over the lake which is exactly how the castle was taken. The poem went:

“Ross may all assault disdain

Till on Lough Lein strange ship shall sail.”

This proved to be true as Ross castle was one of the very last to be taken by Oliver Cromwell’s Roundheads during the Confederate Wars. A ship sailed up the River Laune and into Lough Leane to bring artillery which eventually led to the surrender of the castle.


A tour of the castle interior is essential on any trip to Killarney. With it’s steep winding staircases and well preserved rooms it is like stepping back in time.
