How a WWII sea fort became the sovereign Principality of Sealand
In short: In 1966, a former British army major occupied a concrete platform in the North Sea. What began as a pirate radio station evolved into Sealand, a micronation that continues to assert its sovereignty despite being swallowed by Britain's expanded territorial waters in 1987.
The foundation of Sealand lies in the strategic architecture of World War II. In 1942, Great Britain constructed a series of large sea forts in the North Sea, including Roughs Tower, to defend the nation from Nazi bombers. These outposts were designed to be manned by Royal Navy soldiers, with some installations hosting up to 300 personnel equipped with antiaircraft weaponry. At the time, most of these forts were built within the internationally recognized territorial waters, which extended only 3 nautical miles from the shore. The purpose of these stations was to house British sailors. The structures were built using steel and concrete.
Roughs Tower, the site of Sealand, was uniquely positioned 6.5 nautical miles from the coast, placing it in international waters. By exploiting this gap, Roy Bates, an ex-British army major who became a radio broadcaster, seized the platform during late 1966. His original intent was to establish a pirate radio station, but the venture took a political turn when he declared the platform a sovereign principality in 1967. The platform consists of two towers. These are topped with a steel deck.
The status of Sealand remains a point of contention in international law. While the Bates family has continued to assert their sovereignty for decades, the geopolitical landscape shifted significantly in 1987 when Britain extended its territorial waters. This expansion effectively enveloped the platform within British territory. Despite this, the micronation persists as a symbol of unconventional sovereignty, operating from a structure of reinforced concrete and steel that sits approximately 110 feet above the ocean. The structure features a one-story building for officers. It also contains a kitchen and crew quarters.
