Agnano is a volcanic crater in Napoli, Italy, situated northwest of Naples in the Campi Flegrei region. It was popular among both Greeks and Romans, and was famed for its hot springs, as well as the practice of witchcraft.

A lake formed in the Middle Ages, and this was drained in 1870 to increase arable land and reduce the habitat of the Anopheles mosquito, which carries the malaria parasite. The crater is now home to the Agnano hippodrome and a few hotels.

Naples (Italian Napoli, Neapolitan Nàpule, from Greek - Néa Pólis - meaning "New City"; see also List of traditional Greek place names) is the largest city in southern Italy and capital of Campania Region and the Province of Naples. The city has a population of about 1 million. By one count the metropolitan area of Naples is the second largest in Italy after that of Milan, with over 4,200,000 inhabitants. As with most major cities, various other urban and metropolitan area population figures are also available. The inhabitants are known as Neapolitans, napulitane in Neapolitan, napoletani or poetically partenopei in Italian. It is located halfway between the Vesuvius volcano and a separate volcanic area, the Campi Flegrei, all part of the Campanian volcanic arc.
