French Baroque architecture is the name given to the French architecture during the reigns of Louis XIII (1610–43), Louis XIV (1643–1715) and Louis XV (1715–74).
French Baroque profoundly influenced 18th-century secular architecture throughout Europe. In particular, the Palace of Versailles and the jardin à la française were copied by other courts all over Europe.
Although the open three wing layout of the palace was established in France as the canonical solution as early as the 16th century, it was the Palais du Luxembourg (1615–20) by Salomon de Brosse that determined the sober and classicizing direction that French Baroque architecture was to take. For the first time, the corps de logis was emphasized as the representative main part of the building, while the side wings were treated as hierarchically inferior and appropriately scaled down. The medieval tower has been completely replaced by the central projection in the shape of a monumental three-storey gateway. De Brosse's melding of traditional French elements (e.g., lofty mansard roofs and complex roofline) with some italianate quotations (e.g., ubiquitous rustication, derived from Palazzo Pitti in Florence) came to characterize the Louis XIII style.
Probably the most accomplished formulator of the new manner was François Mansart, a tireless perfectionist credited with introducing the full Baroque to France. In his design for Château de Maisons (1642), Mansart succeeded in reconciling academic and baroque approaches, while demonstrating respect for the gothic-inherited idiosyncrasies of the French tradition. Maisons-Laffitte illustrates the ongoing transition from the post-medieval chateaux of the sixteenth century to the villa-like country houses of the eighteenth. The structure is strictly symmetrical, with an order applied to each story, mostly in pilaster form. The frontispiece, crowned with a separate aggrandized roof, is infused with remarkable plasticity and the whole ensemble reads like a three-dimensional whole. Mansart's structures are stripped of overblown decorative effects, so typical of contemporary Rome. Italian Baroque influence is muted and relegated to the field of decorative ornamentation.
