About Foundation Day in San Marino
In San Marino, Foundation Day is a nationwide public holiday and civic observance centred on the republic’s origins. It is especially significant because it connects the modern state with its traditional founding narrative and the identity of San Marino as one of the world’s oldest republics. The day falls on the same date as the country’s national feast day, so it is closely associated with state ceremony and national symbolism.

San Marino traces its foundation to the traditional account of Saint Marinus, a stonemason who settled on Mount Titano and established a small Christian community. Over time, that settlement developed into the Republic of San Marino, and 3 September became the date used to commemorate its founding.
