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.
Neoclassicism in France
Beginning in the 1770s, the "style pompéien" or Pompeii style came into fashion in Paris, based on reproductions of designs found in Pompeii, augmented with arabesques, griffons, sphinxes, horns-of-plenty and vases on tripods, interlaced with vines and medallions and painted on tall rectangular panels on the walls painted white and bordered with gilded stucco. The new style also took inspiration from the decorative grotesques of Raphael painted at the Vatican in 1510. The boudoir of Marie-Antoinette at the Palace of Fontainebleau, designed by Rousseau de la Routière in 1790, just after the Revolution began, is a notable example.
