The Principality of Sealand is located on an anti-aircraft defense gun platform which was built in 1943 but fell into disuse after WWII. At the time it was located in international territorial waters, approximately 12 kilometres off the coast of England. In 1967 Former British major Roy Bates seized the platform from a group of pirate radio broadcasters with the intention of setting up his own station at the site, but he never made any broadcasts. Instead he declared the platforms independence and named it the Principality of Sealand. Since 1987, Sealand lies within the territorial waters of the United Kingdom.
