The coat of arms of San Marino probably originated in the fourteenth century, and can be seen as a whole as a symbol of freedom and independence of the oldest republic in the world. The components of the coat of arms are in detail:

• In the blue shield there are three green mountains with three silver towers, which are decorated with a weather vane with a silver ostrich feather. The towers symbolize the three citadels of San Marino (La Guaita, La Cesta and La Montale), while the hills represent the three summits of the Monte Titano.
• The motto LIBERTAS (Lat. Freedom). It possibly refers to the taking in of victims of political persecution in the earlier years of San Marino, and to the amazing maintenance of independence in the midst of many larger states.
• An oak and laurel branch, which surrounds the coat of arms are symbols for the stability of the republic and the defense of the liberty.
• A crown, which serves as symbol of sovereignty.
