Fort Clonque is a 19th-century coastal fortress in Alderney in the Bailiwick of Guernsey in the Channel Islands. It was constructed at a time when French naval power was becoming an increasing concern to the British. It is built on a rocky outcrop of land joined to the island by a causeway that can be submerged at high tide. It was manned by fifty men and fortified with up to ten guns mostly 68-pounders however none was ever fired in anger.
