Origin & history
The Arengo was San Marino's original governing assembly, dating back to the early days of the Republic. According to tradition, in 301 AD, Saint Marinus and a small community of Christians established a refuge on Mount Titano. Over time, they developed a system of self-rule where all heads of households would gather in a public square—the Arengo—to debate and decide on communal matters. This direct democracy became the cornerstone of San Marino's political identity, and the Arengo continued as the supreme authority until the 13th century when it was gradually replaced by the Grand and General Council. The modern holiday was instituted to honor this foundational institution and to remind citizens of their rights and responsibilities in a republic.
Customs & traditions
The holiday is marked by institutional ceremonies and public events. In the morning, officials gather at the Palazzo Pubblico for a formal session of the Grand and General Council, often including a speech by the Captains Regent. The day also features the traditional 'Investiture of the Arengo,' a symbolic reenactment of the ancient assembly where citizens were called to vote on key issues. In some years, a historical parade with participants in medieval costumes recreates the atmosphere of the original Arengo. Other festivities include concerts, exhibitions, and the opening of museums and cultural sites to the public. Many families enjoy traditional Sanmarinese dishes such as 'torta tre monti' (layered cake) and 'passatelli' (egg and breadcrumb pasta).
Why it is celebrated
The Anniversary of the Arengo is a celebration of San Marino's enduring commitment to democracy and civic participation. It reminds citizens that the republic was built on the principle of collective decision-making and that each individual has a role in shaping the nation's future. The holiday fosters national pride and a sense of continuity with the past, reinforcing San Marino's identity as the world's oldest surviving republic.
