Napoleon III style
The Napoleon III style was a highly eclectic style of architecture and decorative arts, which used elements of many different historical styles,and also made innovative use of modern materials, such as iron frameworks and glass skylights. It flourished during the reign of Emperor Napoleon III in France (1852–1871) and had an important influence on architecture and decoration in the rest of Europe and the United States. Major examples of the style include the Opéra Garnier in Paris by Charles Garnier (1862–71), the Bibliothèque nationale de France. and the Church of Saint Augustine (1860–1871). The architectural style was closely connected with Haussmann's renovation of Paris carried out during the Second Empire; the new buildings, such as the opera, were intended as the focal points of the new boulevards.

Napoleon III also built monumental fountains to decorate the heart of the city; his Paris city architect, Gabriel Davioud, designed the polychrome Fontaine Saint-Michel (officially the Fontaine de la Paix) at the beginning of Haussmann's new Boulevard Saint-Michel. Davioud's other major Napoleon III works included the two theaters at the Place du Châtelet, as well as the ornamental fence of Parc Monceau and the kiosks and temples of the Bois de Boulogne, Bois de Vincennes and other Paris parks.
