Palace of Versailles
Royal Apartments

The construction in 1668–1671 of Louis Le Vau 's enveloppe around the outside of Louis XIII 's red brick and white stone château added state apartments for the king and the queen. The addition was known at the time as the château neuf (new château). The grands appartements (Grand Apartments, also referred to as the State Apartments) include the grand appartement du roi and the grand appartement de la reine. They occupied the main or principal floor of the château neuf, with three rooms in each apartment facing the garden to the west and four facing the garden parterres to the north and south, respectively. The private apartments of the king (the appartement du roi and the petit appartement du roi) and those of the queen (the petit appartement de la reine) remained in the château vieux (old château). Le Vau's design for the state apartments closely followed Italian models of the day, including the placement of the apartments on the main floor (the piano nobile, the next floor up from the ground level), a convention the architect borrowed from Italian palace design.

The king's State Apartment consisted of an enfilade of seven rooms, each dedicated to one of the known planets and their associated titular Roman deity. The queen's apartment formed a parallel enfilade with that of the grand appartement du roi. After the addition of the Hall of Mirrors (1678–1684) the king's apartment was reduced to five rooms (until the reign of Louis XV, when two more rooms were added) and the queen's to four.

The queen's apartments served as the residence of three queens of France – Maria Theresa of Spain, wife of Louis XIV, Maria Leszczyńska, wife of Louis XV, and Marie Antoinette, wife of Louis XVI. Additionally, Louis XIV's granddaughter-in-law, Princess Marie-Adélaïde of Savoy, duchess of Burgundy, wife of Louis, Duke of Burgundy, occupied these rooms from 1697 (the year of her marriage) to her death in 1712.
