The Gallo-Roman sites of Villasse and Puymin in Vaison-la-Romaine constitute the largest open-air archaeological site in France. It consists of nearly 28 acres (10 ha) of vestiges of public monuments, luxurious residences with porticoed courtyards and gardens, lined streets with shops, or thermal baths, a significant amount of which has not yet been unearthed. The Théo Desplans archaeological museum in Puymin, inaugurated in 1974 and renovated in 1998, exhibits and enhances everyday objects and decorations (sculptures, mosaics, imperial statues from the theater, etc.) unearthed by archaeological excavations. It also recounts the religious and festive practices as well as the funeral rites of the time.
