The Three Towers of San Marino are located on the three peaks of Monte Titano in the capital. They are depicted on both the flag of San Marino and its coat of arms. The three towers are: ''Guaita'', the oldest of the three (it was constructed in the 11th century); the 13th-century ''Cesta'', located on the highest of Monte Titano's summits; and the 14th-century ''Montale'', on the smallest of Monte Titano's summits, still privately owned.
