Amphitheaters, like sports stadiums today, provided entertainment for the Romans. Found in most large cities during ancient times, many amphitheaters have been preserved throughout the ancient world. Not to be confused with the odeon (or Roman theater where actors put on shows wearing masks), the amphitheaters had sports spectacles that included gladiators. From Rome to Naples, other than the Roman Colosseum, you can see these four equally impressive edifices:
The Capua Amphitheater where Spartacus trained;
The Flavian Amphitheater in Pozzuoli and third largest in Italy;
The once privately owned amphitheater at the Grotto di Seiano; and
The mid-sized amphitheater within the ruins of Pompeii.
