The Flavian Amphitheater located in Pozzuoli is the third biggest structure of its kind after the one in Capuano and, of course, Rome’s famous Colosseum. Built in the 1st century AD, it could seat an audience of up to 40,000 people. Some historians claim Emperor Vespasian started it and Titus completed it, while others believe Nero oversaw the entire construction process.

The amphitheater originally had three overlaying levels, four major entrances and 12 secondary ones. It was the center of urban life, and home to a number of professional associations, of which various inscriptions are a clear trace.
