Archaeological Sites in Pozzuoli

In terms of dimensions, the Flavian Amphitheatre in Pozzuoli is the third Roman amphitheatre in Italy, after the Colosseum in Rome and the Campanian Amphitheatre of Santa Maria Capua Vetere.

The edifice known as "Temple of Serapis", in virtue of the the discovery of a statue representing the Egyptian god during the XVIII century, was actually a public market (called Macellum in ancient times), located at the centre of the commercial city-quarter.
