At the south eastern end of the Champs Elysees lie the Grand Palais and the Petit Palais. The Grand Palais is a large glass exhibition hall with an impressive neoclassical stone facade and a riot of Art Nouveau ironwork built for the Paris exhibition of 1900. It was built at the same time as the Petit Palais, a museum in neoclassical style based on a design of Charles Girault. Both palaces are next to the Pont Alexandre III, a monumental and artistic arch bridge connecting the Champs-Élysées and the Invalides and Eiffel Tower districts.
