One of the most beautiful halls in the palace, it has remained virtually unaltered to the present day and features decorations that date back to Charles III's time. The ornamental scheme took about fifty years to finish for a variety of reasons.

It was the location where, in accordance with prevailing custom, the monarch would get dressed in front of the court. Its décor, created by Matas Gasparini, is extremely unique and in the rococo chinoiserie style. The upholstery on the walls, the marble floor, and the furnishings were all created together. Due to its bad state, the silk on the walls recently had to be replaced; nonetheless, the embroidery was painstakingly sewed into the new fabric.

The clock by Pierre Jacquet Droz over the fireplace is noteworthy because it features automatons dancing in 18th-century attire as a seated shepherd plays the flute as the timer goes off. "Jaquet Droz A la Chaux de Fonds en Suisse" is written on the clock face.
