The Paris 1900 "Exposition universelle" marked the high point of Art Nouveau. Between April and November 1900, it attracted nearly fifty million visitors from around the world, and showcased the architecture, design, glassware, furniture and decorative objects of the style. The architecture of the Exposition was often a mixture of Art Nouveau and Beaux-Arts architecture: the main exhibit hall, the Grand Palais had a Beaux-Arts façade completely unrelated to the spectacular Art Nouveau stairway and exhibit hall in the interior.
