The Roman theatre of Orange is built into the hill of Saint-Eutrope. Its stage wall is more than 30 metres high and 100 metres long. The theatre forms part of a site dedicated to the imperial cult and is one of the most evocative of the Roman world. The triumphal arch at the entrance to the town was built during the time of Augustus, bearing witness of Roman settlement in Gaul.
Criterion (iii): Dating back to the time of Augustus, the theatre of Orange is one of the best preserved and largest of all Roman theatres, with its 103-metre-long and 37-metre-high facade. It is an outstanding, if not unique, example of Roman theatres.
Criterion (vi): The triumphal arch of Orange and its bas-reliefs commemorate military victory over the native inhabitants and the establishment of Pax Romana, one of the most celebrated effects of Roman colonization.
