ContentCHAPEL - ISLAND, an extra-parochial liberty, in the barony of BANTRY, county of CORK, and province of MUNSTER, 2 miles ( N. W.) from Bantry ; containing 5 inhabitants.
This island, which is situated in the bay of Bantry, derived its name from a chapel founded on it, of which there are no vestiges except the burial-ground. It comprises about 24 statute acres of extremely fertile land, which is in a high state of cultivation, and as part of the Bandon estate, in which parish it is locally included, is the property of the Duke of Devonshire. There is only one house on the island, which is occupied by the farmer who manages the land. Though nearly adjoining Hog and Horse islands, which also belong to the duke, it is more than 30 miles front any other portion of the Bandon estate.
