The Hall of Mirrors (French: Grande Galerie or Galerie des Glaces) is the central gallery of the Palace of Versailles in Versailles, France.
As the principal and most remarkable feature of King Louis XIV of France's third building campaign of the Palace of Versailles (1678–1684), construction of the Hall of Mirrors began in 1678. To provide for the Hall of Mirrors as well as the salon de la guerre and the salon de la paix, which connect the grand appartement du roi with the grand appartement de la reine, architect Jules Hardouin Mansart appropriated three rooms from each apartment as well as the terrace that separated the two apartments.
The principal feature of this hall is the seventeen mirror-clad arches that reflect the seventeen arcaded windows that overlook the gardens. Each arch contains twenty-one mirrors with a total complement of 357 used in the decoration of the galerie des glaces. The arches themselves are fixed between marble pilasters whose capitals depict the symbols of France. These gilded bronze capitals include the fleur-de-lys and the Gallic cockerel or rooster. Many of the other attributes of the Hall of Mirrors were lost to war for financial purposes, such as the silver table pieces and guéridons, which were melted by order of Louis XIV in 1689 to finance the War of the League of Augsburg.
In the 17th century, mirrors were among the most expensive items to possess at the time; the Venetian Republic held the monopoly on the manufacture of mirrors. In order to maintain the integrity of his philosophy of mercantilism, which required that all items used in the decoration of Versailles be made in France, Jean-Baptiste Colbert enticed several workers from Venice to make mirrors at the Manufacture royale de glaces de miroirs. According to legend, in order to keep its monopoly, the government of the Venetian Republic sent agents to France to poison the workers whom Colbert had brought to France.
