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.
Nazi architecture
Nazi architecture is the architecture promoted by the Third Reich from 1933 until its fall in 1945. It is characterized by three forms: a stripped-down neoclassicism (typified by the designs of Albert Speer); a vernacular style that drew inspiration from traditional rural architecture, especially alpine; and a utilitarian style followed for major infrastructure projects and industrial or military complexes. Nazi ideology took a pluralist attitude to architecture; however, Adolf Hitler himself believed that form should follow function and wrote against "stupid imitations of the past".
