Roman Theatre of Orange
The Western Roman Empire declined during the 4th century. Christianity had become the official religion. An official edict closed the theatre in AD 391. This is because at that time the Church was against what it saw as uncivilised performances. The Visigoths probably pillaged it in 412. Like most Roman buildings, a lot of its better stone was used again for other buildings. It was used as a defensive post in the early Middle Ages. By the 12th century, the Church started to use it for religious plays. During the 16th-century there were religious wars. The theatre became a place to hide for the townspeople. In 1981 UNESCO declared the theatre as a World Heritage Site. In modern days, it is used mostly for opera. It is also a tourist attraction.
