Basilica di San Marino
It stands in Piazza Domus Plebis, where there was, already in the fourth century, a parish church dedicated to the Saint. After the demolition, in 1807, it was erected in neoclassical style by the architect Achille Serra. The high altar is adorned with the statue of the Saint by Tadolini (student of Canova) and on his right, in a case, his skull is preserved. The Basilica is depicted on the 10-cent coin.
