King’s State Apartment (Grand Appartement du Roi)
The highlight of a visit to Versailles is entering the King's State Apartment (Grand Appartement du Roi), built for Louis XIV by Le Vau in the 1670s. The King’s Apartment is a succession of salons dedicated to the gods and planets, used for court functions.
The opulent Queen’s Apartments include the private rooms and the golden queen’s bedchamber, whose hidden door was used by Marie-Antoinette to escape the Paris mob during the early days of the Revolution.
The most spectacular room in the entire palace is the glittering Galerie des Glaces (Hall of Mirrors). The baroque mirror-lined hall was designed by Mansart in 1678, and features mirror-lined arched windows and gilt sculptures holding aloft crystal chandeliers.
The Treaty of Versailles was signed in the Hall of Mirrors at the end of World War I.
