The Roman theater of Vaison-la-Romaine was dug in the first century AD on the northern slope of the hill of the Puymin site, suitable for its installation. The other three slopes of the hill were occupied by large residences and craft districts. Reorganized during the second century, the theater was active until its abandonment linked to the advance of Christianity in the region. It was then gradually transformed into a stone quarry before being rediscovered in 1821 by the designer Chaix in charge of research about the ancient monuments of the Vaucluse department.
