The Palais Bourbon, a palace located on the left bank of the Seine, across from the Place de la Concorde, is the seat of the French National Assembly, the lower legislative chamber of the French government. The palace was originally built (1722-1728) for the legitimised daughter of Louis XIV and Françoise-Athénaïs, marquise de Montespan – Louise-Françoise de Bourbon. During the French Revolution the Palais Bourbon was nationalized.
