The Duomo, the cathedral of Naples, is dedicated to San Gennaro, Saint Januarius, the patron saint of the city. It was built at the end of the 13th century at the decree of Charles I of AngiĆ² near the basilica of Santa Restituta (of which more, below), a sixth-century church that was incorporated into the Gothic architecture of the later cathedral, itself.
