What is recorded here

Arkin's Castle stands in Cill Éinne on Inis Mór, where Oliver Cromwell's forces built a fort in the 1650s to guard Galway Bay. It replaced an older O'Brien stronghold and later held outlawed priests, but only one of its four watchtowers still rises above the sea. The name aircín points to a small natural harbour, suggesting the stones grew from water rather than pride.

Arkin's Castle is recorded as a castle in County Galway. Its open map record supplies this location and any linked names or public references.

Arkin's Castle was built in the 13th century by the de Burgo family, Norman lords who held significant lands in Connacht. It is remembered as part of the medieval Norman settlement in Galway and reflects the strategic expansion of Norman influence into western Ireland during the late Middle Ages.
