The National Center of Stage Costume is the first preservation structure, in France or abroad, to be entirely devoted to the material heritage of theaters.

Its mission is the preservation, study and valorization of a heritage collection of 10,000 theater, opera and ballet costumes in addition to painted stage sets, provided by the three founding institutions of the center, the National Library of France, the Comédie-Française and the National Opera of Paris. The center has also received numerous donations from artists and theaters.
