The Peace Room features the same decoration of marble panel and trophies of gilded bronze and carved weapons as in the War Room, to which is symmetrical. However, Le Brun decorated the cupola and the ceiling panels with the benefits of the peace given to Europe by France. At the end of the reign of Louis XIV, this room was separated from the hall by a mobile partition and considered part of the Queen’s Grand Apartment, of which it became the last room. It was here that, under the reign of Louis XV, Marie Leszczinska gave lay or religious concerts every Sunday, which played an important role in the musical life of Versailles, and which were perpetuated under the reign of Marie-Antoinette.
