The Basilica of Saint Marinus is San Marino’s main sacred building and preserves the relics of Saint Marinus, the microstate’s patron and founder. The present basilica, built in the early 19th century, is Neoclassical in style and is fronted by austere Corinthian columns. To the right of the basilica, on the Piazza Domus Plebis, is the 16th-century Church of St Peter, remodelled around 1826.
From Easter until October a mass is held daily at 4pm in Italian, English, Spanish and Latin.
