The Galerie des Machines (Industry Hall), designed by Joseph-Antoine Bouvard, was among the grandest structures built for the 1889 Exposition Universelle. Ornate polychrome decor masked the central dome’s metal engineering, in contrast to the explicitly modern Eiffel Tower, the base of which is visible in the background of this image through a paned-glass wall. Louis Béroud shows a variety of figures—including soldiers (both French and North African), fashionable European men and women, and people in regional dress—traversing the vast hall, signaling the cosmopolitanism of Paris. The painted frieze circling the dome’s upper level similarly represents a parade of nations.
