<P> The king 's apartment consisted of an enfilade of seven rooms , each dedicated to one of the then known planets and their associated titular Roman deity . The queen 's apartment formed a parallel enfilade with that of the grand appartement du roi . It served as the residence of three queens of France - Marie - Thérèse d'Autriche , wife of Louis XIV , Marie Leczinska , wife of Louis XV , and Marie - Antoinette , wife of Louis XVI . Additionally , Louis XIV 's granddaughter - in - law , Princess Marie - Adélaïde of Savoy , duchesse de Bourgogne , wife of the Petit Dauphin , occupied these rooms from 1697 ( the year of her marriage ) to her death in 1712 . 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 . </P>
