Maunsell Army Sea Forts - Whitstable - England

Part of the Thames Estuary defense network, the anti-aircraft tower-forts were constructed in 1942, with each fort consisting of a cluster of seven stilted buildings surrounding a central command tower. When operational, catwalks connected the buildings. After their successful wartime career, the forts were decommissioned in the 1950s.

In the 1960s and 70s, the remaining abandoned forts were famously taken over as pirate radio stations. The micro nation Principality of SeaLand occupies a nearby Navy fort of a different design known as the Roughs Tower, also by Maunsell. All of the Army Forts are now abandoned.
