Louis Le Vau (19 February 1612 – 11 October 1670) was a French Classical architect who worked for Louis XIV of France. He was born and died in Paris.
He was responsible, with André Le Nôtre and Charles Le Brun, for the redesign of the château of Vaux-le-Vicomte. His later works included the Palace of Versailles and his collaboration with Claude Perrault on the Palais du Louvre. Le Vau also designed two mirroring additions across the Parterre to the evergrowing Château de Vincennes, the Château du Raincy, the Hotel Tambonneau, the Collège des Quatre-Nations (now housing the Institut de France), the church of St. Sulpice, and Hôtel Lambert, on the Île Saint-Louis, Paris.
