The amphitheatre has an elliptical base, with four main entrances and twelve secondary doors, which allowed access to the steps.
It was a medium-sized theater - it could hold about 15,000 spectators - and was mainly intended for gladiator fights and hunting spectacles.
Of the four main entrances, the one to the north was the famous gladiator's gate, from which the ancient victorious warriors used; the one to the south, on the other hand, was intended for the exit of the killed gladiators and the carcasses of the fairs.
