The Cathedral of S. Maria Assunta is a monumental basilica and cathedral of the city of Naples. The cathedral stands along the eastern side of the street of the same name, in a small square surrounded by porticoes, and incorporates two other religious buildings that arose independently of the cathedral as side chapels: the Basilica of Santa Restituta, which houses the oldest baptistery in the 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 superposition of several styles ranging from the pure Gothic of the fourteenth century to the neo-Gothic of the nineteenth century, and from a folkloristic profile, in fact hosting the rite of the liquefaction of the blood of San Gennaro three times a year.
