Déclassement was a group exhibition, curated by Barbara Sirieix, that looked at contemporary protocols for cultural heritage. The site for this exhibition, Chateau d'Oiron, is notable in having a dual status as a historical monument and contemporary art collection, which includes works by On Kawara, James Lee Byars, and others. The artists invited to participate in Déclassement were encouraged to respond to the particular conditions of the site and explore subjects like conservation and restoration.
