The Duomo of Naples, officially the Cathedral of Santa Maria Assunta, is the city's main place of worship and stands along the street of the same name, Via Duomo. The current structure is a layering of styles ranging from the Gothic of the 14th century to the Neo-Gothic of the 19th-century facade. Inside, it houses the Royal Chapel of the Treasury of San Gennaro, where the relics and the ampoule with the blood of the patron saint are kept. The complex also includes the ancient basilica of Santa Restituta and the Baptistery of San Giovanni in Fonte, considered the oldest in the West.

The castle originally took the name Castrum Gironis: according to some from the name of Hieron of Syracuse (to whom the first settlement dating back to the 5th century BC is attributed), according to others from the "circumference of walls" fortified that surrounded the small island of trachyte rock.

The Gulf of Pozzuoli is a cove located near the city from which it takes its name, Pozzuoli. The gulf is entirely contained within the Gulf of Naples. It winds between Cape Miseno and Cape Posillipo: the distance between the two points is about 6 kilometers. The area concerned is that of the Phlegraean Fields. Geology The main phenomenon affecting the gulf is bradyseism, which in the eighties made it necessary to move the port 50 meters forward from its original location and which is the origin of the archaeological finds from the Roman era of parts of the city now underwater. Monitoring Since 2008, a system for monitoring marine volcanoes called "CUMAS" (Cabled Underwater Module for Acquisition of Seismological data) has been present in the center of the gulf, at a depth of one hundred meters, which is connected in real-time to the monitoring room of the Vesuvius Observatory.

Lake Averno is a lake of volcanic origin located near Pozzuoli, according to myth the gateway to the underworld, probably due to the sulfurous fumes that rose from it in antiquity. The lake is visited by AENEAS! in the Aeneid, guided by the Sibyl, to reach the Kingdom of the Dead. Historically, in the Augustan age, it became the site, along with the nearby Lake Lucrino, of the so-called Portus Iulius, a military port of which it constituted the inner basin. Subsequently abandoned due to the easy silting up of the access, it was incorporated into the Ripa Puteolana, the complex of docks of the commercial port of Puteoli. Along its shores stands the so-called "Temple of Apollo", actually a hall of a vast thermal complex, one of the numerous facilities that arose in the Phlegraean Fields to also exploit the natural heat sources.

Many art treasures in this cathedral. "The Cathedral of Naples (Italian: Duomo di Santa Maria Assunta) is the main church of Naples, dedicated to the Assumption of the Virgin Mary. The relics of San Gennaro (January), the patron saint of Naples, are also kept here, which is why it is also known as the Duomo di San Gennaro." (Wikipedia) The cathedral also has very modern and clean restrooms.
