It's easy to admire the grace and engineering of this theatre – built at the behest of the unofficial first Roman Emperor, Augustus, in the 1st century BC, despite a semi-ruinous state brought on by centuries of pilfering. It still serves as one of Arles' premier venues, staging summertime concerts and plays where lighting, seating for 10,000 and the few remaining pillars create a magical atmosphere. The entrance and ticket office is on rue de la Calade.
