Rose Island was a short-lived micronation on a platform in the Adriatic Sea, seven miles off the coast of Rimini, Italy.
In 1964, Italian engineer Giorgio Rosa built the 400-meter-square platform, supported by nine strong pylons on the seabed. Reportedly, this platform eventually housed a restaurant, a bar, a night club, a souvenir shop, a post office, and perhaps a radio station.
The artificial island declared independence on 24 June 1968, under the Esperanto name "Insulo de la Rozoj". Stamps, currency, and a flag were produced.
The Italian government sent troops to crush the rebellion. Two carabinieri and two inspectors of finances landed on the "Isole delle Rose" and took over the just-born state. The platform's Council of Government sent a telegram to protest against the violation of its sovereignty, and the injury inflicted on local tourism by such a military occupation, but this was ignored. The island was destroyed by the Italian Navy.
Rose Island's flag was orange, with a white shield in the center bearing three red roses with green leaves and stems.
