The Flavian Amphitheater (Anfiteatro Flavio Puteolano), located in Pozzuoli in Campania (south central Italy), shapes the third largest Roman amphitheatre on nowadays Italian soil behind the Roman Colosseum in Rome and the Amphitheatre of Capua.
Construction commenced under emperor Vespasian (69-79 AD) and apparently finished during the short reign of his son Titus (79-81 AD), likely designed by the same architects as the Roman Colosseum, over the second half of the first century AD.
The nearly intact interior features an elliptical arena that roughly measures 72 x 42m and the venue could host up to a good 50000 spectators in its heyday.
It was actually the second Roman amphitheatre to be built in Pozzuoli since there was the earlier Anfiteatro Minore, likely built in the late first century BC or early first century AD, but didn’t meet demands to stage gladiator events.
