The first, the Paris Universal Exposition of 1878, occupied the Champ-de-Mars, the hill of Chaillot on the other side of the Seine, and the esplanade of the Invalides. The central building, the Palais de Trocadero, was constructed in a picturesque neo-Moorish or neo-Byzantine style by architect Gabriel Davioud, whose other notable works, built for Napoleon III, included the two theaters on the Place du Chatelet and the Fontaine Saint-Michel. The palace was used in all three Expositions of the Belle Époque, but was finally demolished in 1936 to make room for the modern Palace of Chaillot.
