It is a long gallery that stretches over 240 feet, with 17 mirrored arches that reflect the light from 350 windows onto the glittering chandeliers and gilded decorations. The Hall of Mirrors was designed by Jules Hardouin-Mansart in 1678 to serve as a place of celebration and reception for the king and his court. It was also used for official ceremonies, such as the signing of the Treaty of Versailles in 1919, which ended World War I. Today, visitors can admire the intricate decoration of the hall, which includes paintings and sculptures depicting important events from French history.
