Pozzuoli is a coastal town at the northwestern end of the Gulf of Naples, in the Phlegrean Fields area, an area of high volcanic activity.

From the port of the modern city, leave the boats for the islands of Ischia and Procida.

In 531 BC, Greeks from the island of Samos (in the Aegean Sea), together with people from the nearby Greek colony Cumes founded Dikaiarkheia (the City of Command by Justice), the future Puteoli. It was the port of Cumae.
Pozzuoli became Roman in 194 BC, with a very good harbor, with a series of ponds, a jetty, and protected from the south winds.
One can see remains of the important Roman port scattered in the modern city.
Overlooking the city, stands the Flavian Amphitheater. It is the third largest in Italy, dating back to the first century, and can accommodate 40,000 spectators.
