The San Marino Flag was adopted on April 6, 1862. The flag is divided into two horizontal bands coloured white on the top and blue on the bottom. In the center of the flag is the coat of arms of San Marino. On the center of the coat of arms is a shield with a depiction of three green mountains with three silver towers on them. The towers are decorated with a weather vane with a silver ostrich feather. The three towers symbolize the three towers of San Marino; La Guaita, La Cesta and La Montale. At the bottom of the shield there is a white banner with the word “Libertas” (freedom). On the sides of the shield is a oak and laurel branch that stand for the stability of the republic and the defense of liberty. At the very top of the shield there is a crown to symbolize San Marino’s sovereignty.
