Claude Perrault's Colonnade is the easternmost façade of the Palais du Louvre in Paris. It has been celebrated as the foremost masterpiece of French Architectural Classicism since its construction, mostly between 1667 and 1670. Cast in a restrained classicizing baroque manner, it interprets rules laid down by the ancient Roman architect Vitruvius, whose works Perrault had translated into French. Architect Louis Le Vau and artist Charles Le Brun also contributed to the realization of Perrault's work.
