The Roman amphitheatre in Verona that is traditionally described as the third-largest surviving Roman amphitheatre is the Verona Arena.
Completed around AD 30, the Arena was built outside Verona’s original city walls, probably during the reign of Emperor Tiberius. Its elliptical structure measures roughly 152 by 123 metres and once held about 25,000 spectators for gladiatorial contests, public spectacles, and other performances.
The familiar “third-largest” description usually means third-largest in Italy, after Rome’s Colosseum and the Amphitheatre of Capua. Rankings can vary when comparing surviving amphitheatres by outer dimensions, capacity, or amount preserved; some modern measurements place Verona lower. That qualification does not change the landmark’s identity.
A major earthquake in 1117 destroyed most of the Arena’s outer ring, leaving the distinctive wing-like fragment visible today. Its interior remains remarkably intact and has hosted the Arena di Verona opera festival since 1913.
