Flag of San Marino. | San Marino claims to be the oldest surviving sovereign state and constitutional republic in the world, as the continuation of the monastic community founded on 3 September 301, by stonecutter Marinus of Arba. Legend has it that Marinus left Rab, then the Roman colony of Arba, in 257 when the future emperor, Diocletian, issued a decree calling for the reconstruction of the city walls of Rimini, which had been destroyed by Liburnian pirates.
The Flag of San Marino. The state and war flag of San Marino is formed by two equal horizontal bands of white (top) and light blue with the national coat of arms superimposed in the center; the coat of arms has a shield (featuring three towers on three peaks) with a closed crown on top, flanked by an oak and laurel wreath, with a scroll below bearing the word LIBERTAS (Liberty). The two colors of the flag represent peace (white) and liberty (azure).
