The apartments of the King were the heart of the chateau; they were in the same location as the rooms of Louis XIII, the creator of the chateau, on the first floor (second floor US style). They were set aside for the personal use of Louis XIV in 1683. He and his successors Louis XV and Louis XVI used these rooms for official functions, such as the ceremonial "lever" ("waking up") and the "coucher" ("going to bed") of the monarch, which were attended by a crowd of courtiers.
