The style Louis XIV, also called French classicism, was the style of architecture and decorative arts intended to glorify King Louis XIV and his reign. It featured majesty, harmony and regularity. It became the official style during the reign of Louis XIV (1643–1715), imposed upon artists by the newly established Académie royale de peinture et de sculpture (Royal Academy of Painting and Sculpture) and the Académie royale d'architecture (Royal Academy of Architecture). It had an important influence upon the architecture of other European monarchs, from Frederick the Great of Prussia to Peter the Great of Russia. Major architects of the period included François Mansart, Jules Hardouin Mansart, Robert de Cotte, Pierre Le Muet, Charles Perrault, and Louis Le Vau. Major monuments included the Palace of Versailles, the Grand Trianon at Versailles, and the Church of Les Invalides (1675–1691).
