The Exposition occupied two large sites. The main site was on Champs de Mars on the Left Bank, which had been the parade ground of the Ecole Militaire, and had been occupied by the 1878 Universal Exposition. This was the site of the major part of the Exposition, including the Eiffel Tower, Palace of Machines, and the Palaces of Fine Arts and Liberal Arts. The Exposition extended across the Seine to the right bank, to the Trocadero Palace, which had been built on the heights for the 1878 Exposition. The slope from the Trocadero Palace down to the Seine was filled with terrace, fountains, gardens and horticultural exhibits.
