Métro Palais Royal-Musée du Louvre is probably the most photographed Métro entrance in Paris. It was redesigned by Jean-Michel Othoniel in 2000 for the centennial of the Métro as the "Kiosque des Noctambules" (Kiosk of the night-walkers). There are two crowns constructed of glass and aluminum -- one representing "day" and the other "night."

The bench concealed under the canopy of "night" was part of the artist's installation for "chance encounters."
