The Feast of San Marino and the Republic

The holiday commemorates the traditional founding of San Marino on September 3, 301 AD, by Saint Marinus, a Christian stonemason fleeing persecution under Emperor Diocletian. According to legend, Marinus took refuge on Mount Titano, where he built a small church and established a community that eventually became the world's oldest surviving republic. The date was chosen because it marks the day when Marinus is said to have died, or alternatively, the day the republic was formally recognized.

Over the centuries, the Feast of San Marino and the Republic evolved from a local religious celebration into a national holiday that underscores the country's enduring sovereignty and republican traditions. The event was officially designated as a public holiday in modern times to reinforce national identity and historical continuity.

The day begins with a solemn Mass in the Basilica of San Marino, attended by government officials, diplomats, and citizens. Afterwards, a grand procession marches through the historic streets of the City of San Marino, featuring the Captains Regent (heads of state), the Guardia di Rocca (Rock Guard) in ceremonial uniforms, and representatives of the country's ancient institutions. The procession culminates in Piazza della Libertà, where the Captains Regent deliver a speech and review the troops.

Throughout the day, cultural events such as concerts, medieval reenactments, and exhibitions take place. Locals and visitors enjoy traditional foods like piadina (flatbread) filled with cheese, prosciutto, or vegetables, and torta tre monti (a layered cake symbolizing the three peaks of Mount Titano). In the evening, fireworks illuminate the sky over the fortress, adding a festive atmosphere.

This holiday is a powerful symbol of San Marino's independence and its unique status as the world's oldest constitutional republic. For citizens, it is a moment to reflect on their heritage, the values of liberty and democracy, and the resilience of a microstate that has survived for over 1,700 years. It also serves to strengthen national pride and unity, as well as to showcase the republic's cultural distinctiveness to the international community.
