Second Empire style, also called the Napoleon III style, is the highly eclectic architecture and decorative-arts style of the Second French Empire. Flourishing under Napoleon III (1852-1870), it drew freely on Renaissance, Baroque, and Neoclassical forms while making innovative use of modern materials such as iron frameworks and glass skylights. It was closely tied to Haussmann's renovation of Paris: grand new buildings like the Opéra Garnier were placed as focal points at the ends of the new boulevards. From France the style spread across Europe and North America, where its tall mansard-roofed public buildings became the signature of civic ambition - from Philadelphia City Hall to the State, War, and Navy Building in Washington. Its blend of historicist splendor and modern engineering made it the defining official style of the mid-nineteenth century.
