Fenit Island is a populated island, on the coast of County Kerry, connected to the mainland by a sandbar. Located in Tralee Bay, the island encloses Barrow Harbour. Historically, the area was called 'Fenit Within'. It is adjacent to the areas of 'Tawlacht' and 'Fenit Without' on the mainland. The terms within/without refer to the walled protection that surrounded parts of the island from attackers from the landward side.
