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.
Little that could be called Baroque can be identified in Perrault’s cool classicism that looks back to the 16th century. The façade, divided into five parts, is a typical solution of French classicism. The simple character of the ground floor basement sets off the paired Corinthian columns, modeled strictly according to Vitruvius, against a shadowed void, with pavilions at the ends. This idea of coupled columns on a high podium goes back as far as Bramante. Those rhythmical columns form a shadowed colonnade with a central pedimented triumphal arch entrance raised on a high, rather defensive base. Crowned by an uncompromising Italian balustrade along its distinctly non-French flat roof, the whole ensemble represents a ground-breaking departure in French architecture.
