The Arena di Verona is located in Piazza Bra in Verona, Italy. It was built in 30 AD and is an ancient Roman open-air theater. It is extremely well preserved and is the best of its kind. In ancient times, it could accommodate nearly 30,000 people, but nowadays, due to safety considerations, the performance capacity is limited to 15,000 people. With its excellent acoustics, it often hosts large-scale opera performances. The opera festival from June to August every year is particularly famous, with many classic repertoires performed in turn.
