The Grand Palais, on the right bank, officially the Grand Palais des beaux-arts et des arts decoratifs, was built upon the site of the Palace of Industry of the 1855 Exposition. It was the work of two architects, Henri Deglane for the main body of the building, and Albert Thomas for the portion which now is the Palais de la Découverte, or science museum. Charles Girault designed the Petit Palais facing the Grand Palais.
