Many of the original furnishings were sold in the wake of the French Revolution. Some works of art, including the overdoors from the "Salle des évêques", part of the municipal collections, were destroyed with the museum situated in the Aubette when the Prussian Army shelled the city during the Siege of Strasbourg in 1870. In the 20th century and especially during the reconstruction following the bomb damage of August 1944, a great deal of effort went into locating the surviving missing objects and replacing the lost works with identical or similar pieces. They were supervised by the aforementioned Hans Haug, who had become director of the newly created network of the municipal museums on 1January 1945. Some elements, though, were never restored, such as the stucco of the library. It was lost in 1817 because of leaks through the ceiling; as the only free-standing part of the building, the library has a flat roof.
