Built in the 1st century AD, the Roman Theatre of Orange is one of the best-preserved examples of Roman theatre architecture in the world. It was constructed during the reign of Emperor Augustus and was designed to hold over 10,000 spectators. The theatre was used for various events, including gladiatorial games, religious ceremonies, and of course, theatrical performances. The plays that were performed in the Roman Theatre of Orange were some of the most popular of the time. Some of the most famous plays performed in the theatre include "Phaedra," "Antigone," and "Oedipus Rex" by Sophocles, and "The Eunuch" and "The Menaechmi" by Plautus.
