¿Cual es el país más pequeño del mundo? Ciudad del Vaticano, pero sólo por 60 miseros metros. El principado de Sealand tiene unos escasos 500 metros cuadrados y una población de 27 habitantes según el último censo. Aunque, eso si, no tiene nada que hacer en cuanto a notoriedad e historia frente al vaticano, ya que lo más importante que ha pasado en Sealand desde su fundación en 1967 es que se ha fundado y poco más. ¿Por que? Muy simple, Sealand es un país fundado en lo que fue una especie de torre de vigilancia inglesa en la segunda guerra mundial.
It all started when in 1966 Paddy Roy Bates, a former English army officer, found what amounted to a surveillance fort beyond English territorial waters. In no man’s land. So he settled there with the intention of broadcasting radio and ended up founding his own country. Country that, by the way, has from official website, to facebook group. In addition to the mandatory passports, coins and some other pending international trial (especially for shooting at British ships :D).

The Sealand case had not attracted much attention until the Internet appeared. Of course, of course. This thing about geekism and weirdness on the Internet is a real gem. Websites have even appeared on the Internet claiming to sell official Sealand passports. Of course, Sealand is not recognized by any official body, although its king defends several points why it should be considered a country.

By the way, a few years ago the king abdicated in favor of his son, and when he saw that his most prized possession was a tower in the middle of the sea, he decided to sell it although there is no news that in the end any type of transaction was carried out.
