Video: 123.85ac private island used for grazing…up for grabs off Co. Cork coast

Castle Island is one of the very few privately owned islands and is situated in Roaringwater Bay, off the coast of Schull, in the stunningly beautiful area of west Cork.

The island is located immediately east of the entrance to Schull Harbour and southwest of Horse Island. It is readily accessed from either Schull Harbour or Rossbrin Cove.

The island extends to 123.85ac (50.12ha) and is for sale through joint selling agents Knight Frank and Dominic Daly.


The island was home to a small community of approximately 15 families who were last resident on the island up to the year 1870.

The ruins of the original three clusters of houses which made up the community are situated in three distinct locations; the first at the pier where the original O’Mahony castle stands and the other two at each end of the island.

Agricultural purposes

Castle Island is currently in use for agricultural purposes. It is now used for grazing; however, in the past, tillage was undertaken there.

There are extensive amenities in the area with multiple Harbours in Schull and Baltimore and it also has good shelter in Rossbin and Crookhaven as well as Cape Clear.

According to the selling agents: “Future use of the island could be for private occupancy or tourism-related development or outdoor pursuits and/or agricultural use.”

The property is guiding at €1 million.
