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.
French architecture
During the mid-19th century when Napoleon III established the Second Empire, Paris became a glamorous city of tall, imposing buildings. Many homes were embellished with details such as paired columns and elaborate wrought iron cresting appeared along rooftops. But the most striking feature borrowed from this period is the steep, boxy mansard roof. You can recognize a mansard roof by its trapezoid shape. Unlike a triangular gable, a mansard roof is almost vertical until the very top, when it abruptly flattens. This singular roofline creates a sense of majesty, and also allows more usable living space in the attic. In the United States, Second Empire is a Victorian style. However, you can also find the practical and the decidedly French mansard roof on many contemporary homes.
