Girault had done temporary structures for Exposition Universelle, Paris, of 1889 and of 1900. He also erected two structures that were intended to outlast the 1900 exhibition: the Petit Palais, which was entirely his own work, and the Grand Palais, of which he was principal architect, working in partnership with Henri-Adolphe-Auguste Deglane, Albert Louvet (1860-1936) and Albert-Th'ophile-F'lix Thomas (1847-1907). The two buildings flank the broad Avenue Alexandre III, just off the Avenue des Champs-Elys'es. The facades are interpretations of 18th-century French architecture. Behind exterior facades built entirely of stone, the Grand Palais is in fact one great iron-framed and glass hall (almost 240 metres long). Its plain interior d'cor centres on a grand staircase leading to the upper galleries.
