The Cathedral of Naples.
I would have preferred to take more photos in this very important place of worship in Naples, also because in one of the chapels attached to the church there is the one that houses the treasure of San Gennaro.
Unfortunately there were too many people and a function in progress so I intend to return and expand the gallery.

The Cathedral of Naples, whose official name is the Metropolitan Cathedral of Santa Maria Assunta, is a monumental basilica as well as a cathedral and seat of the archdiocese 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, as side chapels, two other religious buildings that arose independently of the cathedral: 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.
