Maritime History
The Admiralty Pier Turret, or Dover Turret, is an enclosed armoured turret built in 1882 on the western breakwater of Dover Harbour in southeast England. It contains two Fraser RML 16 inch 80 ton guns, the biggest installed in the United Kingdom. Declared obsolete in 1902, it is currently part of the port and inaccessible, though the guns remain in place.
