Charles Julien has been working at the Heritage and Archeology center of Vaison-la-Romaine for nearly thirty years. He endeavors to restore and maintain the ancient archaeological sites of La Villasse and Le Puymin. His work consists of rebuilding degraded elements (columns, stairs, baths, etc.), waterproofing the tops of the walls, and making restitution casts of pieces kept in the museum in order to replace them on the sites.
