The park served again as an exposition site during the Universal Exposition of 1900; it became the home of the Grand Palais and Petit Palais. It also became the home of a new panorama theater, designed by Gabriel Davioud, the chief architect of Napoleon III, in 1858, to display large 360-degree historical paintings. That building became the Palais de Glace, or ice palace, in 1893, and then, after World War II, became a dramatic theater, the Théatre du Rond-Point, which specialized in new French plays. The Théatre Marigny was built by Charles Garnier, architect of the Paris Opera, in 1883, was also originally designed to display panorama paintings. It was turned into a musical theater in 1894.
