After the American Civil War, builders in the United States and Canada looked across the Atlantic to the rebuilt Paris of Napoleon III, and the Second Empire style crossed the ocean to become the face of a confident new official architecture. Popular between 1865 and 1900, it carried the mansard roof - steep, slate-clad, pierced with dormers - over federal buildings, city halls, custom houses, and grand houses from Washington to Quebec. The style drew on the French Renaissance as well as on contemporary Paris, and in the United States it is sometimes called General Grant style after the president under whom federal building boomed. Alfred Mullett's State, War, and Navy Building beside the White House, Philadelphia's enormous City Hall, and Quebec's Parliament Building show its range: heavy massing, elaborate ornament, and a full extra storey hidden in the roof.
