also: Second Empire style · Napoleon III style
Second Empire architecture takes its name from the France of Napoleon III (1852-1870), whose rebuilding of Paris gave the style its showcase. Rooted in the French Renaissance and Baroque, it reached its greatest European popularity in the second half of the nineteenth century and lingered into the early years of the twentieth. Its signature is the mansard roof - a steep, double-pitched roof with dormer windows that adds a full extra storey - crowning buildings of high-contrast stonework, heavy cornices, and square-based domes. Charles Garnier's Paris Opéra is the supreme example, but the style dressed railway stations, ministries, theatres, and townhouses across the continent. It reads as confident, official, urban architecture: tall, ornate, and unmistakable on a skyline.
