HM Fort Roughs is one of several World War II installations that were designed by Guy Maunsell and known collectively as His Majesty's Forts or as Maunsell Sea Forts; the purpose of which was to guard the port of Harwich, Essex, and more broadly, the Thames estuary. This 4,500 ton artificial naval installation is similar in some respects to "fixed" offshore oil platforms. It is situated on Rough Sands, a sandbar located approximately from the coast of Suffolk and from the coast of Essex. Today it is the location and de facto capital of the unrecognised, self-proclaimed state of Sealand. Read more on Wikipedia
