Fort Clonque, Victorian coastal fortress in Alderney, Channel Islands
Fort Clonque stands on a rocky outcrop connected to Alderney by a causeway that submerges during high tides, creating a temporary island.
The British government constructed Fort Clonque between 1853 and 1855 as a defense against French naval expansion, equipping it with ten 64-pounder guns.
The Landmark Trust acquired the fort in 1966 and transformed the military structure into accommodation while preserving its historical architecture.
The fort provides sleeping arrangements for thirteen guests across multiple buildings, requiring visitors to plan their arrivals according to tide schedules.
During high tides above 5.7 meters, the causeway disappears underwater, temporarily isolating the fort from the main island of Alderney.
