The Metropolitan Cathedral of Santa Maria Assunta is a monumental basilica as well as the cathedral and seat of the archdiocese of the city of Naples. It is one of the most important and largest churches in the city. Its importance from an artistic point of view is given by the overlapping of several styles ranging from the pure Gothic of the fourteenth century to the neo-Gothic of the nineteenth century; from a cultural point of view instead, it hosts the rite of the dissolution of the blood of San Gennaro three times a year.
The cathedral stands along the east side of the street of the same name, in a small square surrounded by arcades, and incorporates two other religious buildings by way of side chapels: the basilica of Santa Restituta, and the royal chapel of the Treasure of San Gennaro, which preserves the relics of the city's patron saint.
