It was originally built (1615–1645) to the designs of the French architect Salomon de Brosse to be the royal residence of the regent Marie de' Medici, mother of King Louis XIII. After the Revolution it was refashioned (1799–1805) by Jean Chalgrin into a legislative building and subsequently greatly enlarged and remodeled (1835–1856) by Alphonse de Gisors.
