Carrickkildavnet Castle

Near the south end of Anchill Island - which is circled by "Atlantic Drive" - the ruins of Carrickkildavnet Castle, (a 15th C. National Monument) stand on the shores of Achill Sound. Part of a vaulted stone roof and the remains of an old slipway for boats can still be seen. The castle belonged to the legendary Grace O'Malley, who ruled extensive territories in this area in the 16th C.
