https://www.sealandgov.org/ The Principality of Sealand, more commonly known as Sealand, is a micronation that claims Roughs Tower, an offshore platform located in the North Sea approximately 12 kilometres (7.5 mi) off the coast of Suffolk, England, as its territory. Roughs Tower is a disused Maunsell Sea Fort, originally called HM Fort Roughs, built as an anti-aircraft defensive gun platform by the British during World War II.[3][4]

Since 1967, the decommissioned HM Fort Roughs has been occupied by family and associates of Paddy Roy Bates, who claim that it is an independent sovereign state.[3] Bates seized it from a group of pirate radio broadcasters in 1967 with the intention of setting up his own station at the site.[5] He attempted to establish Sealand as a nation-state in 1975 with the writing of a national constitution and establishment of other national symbols.
