The most significant heritage of Verona is undoubtedly the Arena di Verona, an outstanding Roman theatre. Arena di Verona is the second biggest existing Roman theatre after the Colosseum in Rome. In ancient Roman times, the arena's capacity was nearly 30,000 people. Its current capacity is 22,000 seats and it is still one of the most prestigious open venues at global level, which hosts multiple major events such as summer seasons of opera, known as “Arena di Verona Festival” or the opening and closing ceremony of 2026 Milan - Cortina Winter Olympics.
