The Cathedral of S. Maria Assunta is a monumental basilica and cathedral of the city of Naples. The cathedral rises along the east side of the street of the same name, in a small square surrounded by porticos, and incorporates two chapels built independently of the cathedral as side chapels: the basilica of Santa Restituta, which houses the oldest baptistery in Rome. West, that of San Giovanni in Fonte, and the royal chapel of the Treasure of San Gennaro, which preserves the relics of the patron saint of the city. It is one of the most important and largest churches in the city, both from an artistic point of view, it is in fact the overlap of more styles ranging from pure Gothic of the fourteenth century to the nineteenth-century neo-gothic, both under a folkloristic profile, hosting indeed three times a year the ritual of the dissolution of the blood of Saint Gennaro.
