Will there soon be a "little Louvre" in Nancy? Such is the ambitious project of extension and renovation entrusted to P.C. Dubois in 2013. The objective is to transform this museum dedicated to the history of the Lorraine region into a genuine "Ducal Palace 2.0". When reopened, digital devices will take the limelight (making it possible to showcase objects that have been lost or to recreate incomplete objects), side by side fantastic permanent holdings.
