The Maunsell Army Sea Forts
Kent, England
These decaying structures are a reminder of the darkest days of WWII. As a part of the Thames Estuary defines network, these anti-aircraft tower-forts were built in 1942, with each fort consisting of seven buildings on stilts, surrounding a command tower. When operational, catwalks connected the buildings.
After the war, the towers were decommissioned in the 50’s, and have served as pirate radio stations and secret hideouts for sovereign citizens.
