Sealand  is a sea fort in the North Sea, located 10 km off the coast of Suffolk, England. It is best known for its (unrecognized) claim to be the world's smallest sovereign nation. However, it is currently regarded as a micronation by most non-Sealanders.
Long entirely off-limits to tourists, the U.K. travel company Church & East now take booking for visits for groups of 1-5 people. An entry visa costs $100 Sealand dollars (£50), the return transfer from Suffolk SX$120 and a day trip/one-night/two-night stay (full board) SX$100/200/300 per person.
Walk. The entire habitable area of the fort is 550 sq.m.
