Near Ponte Leproso, in 1985 the traces of the great Roman amphitheatre came to light where, according to Tacitus, the emperor Nero attended a gladiator show in 63 AD.

Therefore, the construction could be located between the 1st century BC and the 1st century AD. Gladiator shows took place and it was perhaps also a school of gladiators. The earthquakes located in the late imperial period made it unusable, while the valuable materials for construction were used for subsequent works.
