Seven nautical miles off Harwich, a World War II anti-aircraft platform called Roughs Tower sits on stilts in the North Sea, declared the sovereign Principality of Sealand in 1967, just ahead of a British attempt to extend territorial waters and shut the claim down. Commissioned by Sealand itself in 2003, this short film gives a tour of daily operations on the platform: security, power generation, and the small crew who keep the place running. It covers the practical case for calling it a nation, its de facto recognition among other states, and its appeal to internet businesses operating outside conventional jurisdiction, including the file-sharing site The Pirate Bay's since-abandoned interest in buying it outright. A fire that damaged the structure in the mid-2000s gets addressed too, along with the wind turbines installed afterward to supplement power. Because Sealand made the film about itself, it plays as much like a pitch for legitimacy as a documentary, but the footage of the fortress and its handful of residents is the real record here.
