Introduction to the bedrooms of the Crown Prince and Princess: The bedrooms of the Crown Prince and Princess are located on the ground floor of the castle, leading directly to the Queen's bedroom on the upper floor through several stairs. They are usually reserved for important members of the royal family. Its current situation is basically the same as when Louis XV's son (Louis, Crown Prince of France) and his second wife Marie-Joseph of Saxony lived here from 1747 to 1765. When the Revolution broke out, the young crown prince, the future Louis XVII, and his sister Madame Royal also hid here.
