Flag of San Marino

San Marino's flag features two horizontal bands of equal height. The upper band is white, while the lower band is light blue. Superimposed in the center is the coat of arms of San Marino, crowned and surrounded by a wreath.

The white stripe on the flag represents peace and purity, reflecting San Marino's commitment to neutrality and its virtuous history. Conversely, the light blue stripe symbolizes liberty and the country's dedication to freedom. The coat of arms at the center embodies San Marino's sovereignty and its historic claim to independence, with the three towers representing the three fortresses of the nation: Guaita, Cesta, and Montale.

The current flag of San Marino was officially adopted on April 6, 1862. Prior to this, various banners and pennons were used, often based on the colors of the ruling families or religious symbols. The 1862 adoption coincided with a period of national consolidation and modernization for the republic. No significant changes have been made to the flag's design since its initial adoption.
