	Beyond the mansard roof, Second Empire buildings display rich classical ornament: columns, pilasters, entablatures, and sculptural decoration that draw from French Renaissance and Baroque precedents. Facades are typically symmetrical and highly articulated, with projecting and receding sections creating dynamic compositions. Materials vary from stone for major public buildings to brick and wood for residential structures, with iron cresting often crowning the mansard roofs. ~~The overall effect suggests~~ French elegance and urban ~~sophistication—qualities that appealed~~ to Americans seeking cosmopolitan alternatives to English architectural traditions.<ref name="tatum"/>		Beyond the mansard roof, Second Empire buildings display rich classical ornament: columns, pilasters, entablatures, and sculptural decoration that draw from French Renaissance and Baroque precedents. Facades are typically symmetrical and highly articulated, with projecting and receding sections creating dynamic compositions.

All of this—the soaring lines, the elaborate detail, the polished surfaces—suggested French elegance and urban sophistication to Americans seeking cosmopolitan alternatives to English architectural traditions.<ref name="tatum"/>

	Philadelphia City Hall represents Second Empire architecture at its most monumental and prolonged. Designed by architect John McArthur Jr. and begun in 1871, the building required nearly thirty years to complete, finally opening in 1901 as the style had long passed from fashion. Yet the ~~building's~~ protracted construction resulted in a structure of remarkable completeness and consistency, its Second Empire character maintained through changing administrations and architectural trends. At 548 feet to the top of the William Penn statue, City Hall ranked as the world's tallest habitable building at completion.<ref name="moss"/>		Philadelphia City Hall represents Second Empire architecture at its most monumental and prolonged.

	The ~~building's~~ granite and marble facades display the full Second Empire vocabulary: mansard roofs at multiple levels, elaborate dormers, columned pavilions, sculptural ornament, and a tower that rises through classical stages to its statue-crowned apex. Sculptor Alexander Milne Calder created over 250 sculptural figures for the building, including the 37-foot bronze William Penn that tops the tower. ~~The interior features~~ equally elaborate ~~decoration, with marble~~ corridors, painted ceilings, and ornamental plasterwork throughout.

	Philadelphia's Second Empire rowhouses display various treatments of the mansard roof: straight slopes with single dormers, curved profiles with double dormers, and elaborate cresting that silhouettes against the sky. Facades below the roofline often remain relatively simple, concentrating ornament on door surrounds and window hoods while the mansard provides visual drama. These houses survive throughout the city, though many have lost their original iron cresting and some have had dormers altered. Where intact, Second Empire rowhouse blocks create coherent streetscapes that document the style's widespread popularity.<ref name="moss"/>		Philadelphia's Second Empire rowhouses display various treatments of the mansard roof: straight slopes with single dormers, curved profiles with double dormers, and elaborate cresting that silhouettes against the sky.

	Second Empire served institutional purposes throughout Philadelphia during the post-Civil War decades.

'''Second Empire Architecture''' achieved its most ambitious American expression in Philadelphia through City Hall, the massive municipal building whose mansard roofs and French-inspired ornament dominated the city's skyline for over a century. Named for the reign of Napoleon III (1852-1870), when Baron Haussmann transformed Paris into a city of grand boulevards and uniform building facades, Second Empire brought French sophistication to American cities during the post-Civil War decades. The style's defining element—the mansard roof with its steep lower slopes and dormer windows—provided both practical benefits and fashionable appearance, making it popular for everything from rowhouses to public buildings across Philadelphia.<ref name="tatum">{{cite book |last=Tatum |first=George B. |title=Penn's Great Town: 250 Years of Philadelphia Architecture |year=1961 |publisher=University of Pennsylvania Press |location=Philadelphia}}</ref>
