* Annexes to the Saint-Saëns hall: there are two small halls located at the end of the Saint-Saëns. The upper part of the walls is adorned with ultramarine blue wallpaper with floral motifs in gold ochre elaborated in vegetable fibre imitating velvet. All of this is to make a reproduction of the sumptuous materials that were fashionable in Europe in the 19th century.
