The most important showcase of the French Classicism was the
Palace of Versailles. It was begun in 1624 by Louis XIII as a hunting lodge. In 1634, Louis XIII had it enlarged into a château by his chief architect and engineer,
Philibert Le Roy. In 1661, Louis XIV decided to enlarge it further, without destroying the original. He commissioned
Louis Le Vau and
Charles Le Brun as his architect and designer, and assigned
André Le Nôtre to create a grand formal garden that could be viewed from the Château, on the model of Vaux-le-Vicomte. When Le Vau died in 1670, the project was given to his assistant
François d'Orbay, who completed the initial phase in 1674. The new palace surrounded the old brick château, with new wings the north, south and to the rear. The façade, like the new Louvre wing, featured colossal order columns, while the roof was flat with a terrance, decorated with balustrades, pilasters, balconies, statues, and trophies. Beginning in 1674–75, Le Brun created the interior with a small army of painters, sculptors, and decorators. They used marble, polychrome stone, bronze mirrors, and gilded stucco, while Le Brun himself painted the ceiling. The
Hall of Mirrors, constructed in 1678–1680 by
Jules Hardouin-Mansart, the nephew of Francois Mansart, overlooked the new garden. It was also decorated by Le Brun, who completed it in 1684, after which it became the symbol of the entire French Baroque style. The new Palace was open to almost any visitor, and became an immense theatre, where the King carried out his ceremonies, with meticulous protocol, in public view.

Jules Hardouin-Mansart and then
Robert de Cotte erected the
Grand Trianon, on the model of an Italian building, the Marble Trianon. It had a single floor, decorated with plaster and marble, with a flat roof and balustrade. The plan was very simple, with a
peristyle flanked by two wings and two
avant-corps, or sections in advance of the wings. It had a simplicity and purity of form that inspired similar palace buildings across Europe, from
Prussia to Russia. Mansart also completed the
Versailles Orangerie (1684–1686) in a similar style, surrounding a formal garden and pool. The
gardens created by
André Le Nôtre were designed to complement the architecture of the palace and to express, by it geometric alleys, pools, rows of the trees, flower beds and fountains, the mastery of the King over nature. The final piece of the Palace was the
Chapel, begun in 1689 to the designs of Hardouin-Mansart and completed by
Robert de Cotte in 1708–1710. The room was given more space and light by the use of classical columns instead of massive pillars, and by placing the supporting columns on an upper level.
Louis XV continued to add to the Palace, mostly with changes to the interior rooms. His major contribution was the
Petit Trianon by
Ange-Jacques Gabriel. Its austere architecture was a sign of the transition to
Neoclassicism. File:Versailles Chapel - July 2006 edit.jpg|Chapel of the Palace of Versailles by
