The Amphitheater in Pozzuoli is the third largest Roman amphitheater in Italy. Only the Roman Colosseum and the Capuan Amphitheater are larger. It was likely built by the same architects who previously constructed the Roman Colosseum. The name Flavian Amphitheater is primarily associated with the Roman Colosseum.The Amphitheater in Pozzuoli is capable of hosting over 20,000 spectators. Its construction begun under the reign of emperor Vespasian who also initiated the construction of the Colosseum in Rome. Unlike the Colosseum not much remains of the upper ranges of seats but the subterranean areas are very well preserved, including the cages for keeping animals and parts of the mechanisms for lifting them to the arena floor. In the late antique period the arena was abandoned and partly buried under ash following an eruption of the volcano Solfatarain.
