History+
Built in the 1st century AD, the theatre served to spread Roman culture and to distract the populace from political activities. Pantomime and poetry readings were forms of entertainment, often accompanied by stage sets. Performances were accessible to all and free of charge. With the decline of the Roman Empire and the spread of Christianity, the theatre was closed in 391 AD by ecclesiastical decree and subsequently plundered by barbarians. In the Middle Ages, it served as a defensive structure, and during the Wars of Religion in the 16th century, it was used as a refuge. Louis XIV is said to have called the stage facade the most beautiful wall in his kingdom. During the French Revolution, it was used as a prison.
