The Palais-Royal is a former French royal palace located on Rue Saint-Honoré in the 1st arrondissement of Paris. The screened entrance court faces the Place du Palais-Royal, opposite the Louvre. Originally called the Palais-Cardinal, it was built for Cardinal Richelieu from about 1633 to 1639 by architect Jacques Lemercier. Richelieu bequeathed it to Louis XIII, before Louis XIV gave it to his younger brother, the Duke of Orléans. As the succeeding Dukes of Orléans made such extensive alterations over the years, almost nothing remains of Lemercier's original design.

The 1st arrondissement of Paris is one of the 20 arrondissements of the capital city of France. In spoken French, this arrondissement is colloquially referred to as le premier. It is governed locally together with the 2nd, 3rd and 4th arrondissement, with which it forms the 1st sector of Paris (Paris-Centre).
