Located in the historic center of San Marino, a UNESCO World Heritage site, the Museum of Stamps and Coins is a specialized institution dedicated to the rich philatelic and numismatic history of the Republic. The collection includes every stamp series issued by San Marino since 1877 and a vast array of coins and medals. Nearby attractions include the Three Towers of San Marino (Guaita, Cesta, and Montale), which are medieval fortresses offering breathtaking views. The Public Palace (Palazzo Pubblico), the seat of government, is another major monument known for its neo-gothic architecture. Visitors can also explore the Basilica di San Marino. The historic center often hosts events, especially during summer, such as the 'Medieval Days' festival, and the changing of the guard ceremony at the Public Palace is a regular spectacle. Aristocratic palaces line the narrow streets, and other nearby museums include the State Museum and the Museum of Curiosities.
