Temple of Liberty: Building the Capitol for a New Nation
Freedom Triumphant in War and Peace: The Capitol Extended

By the close of the Civil War in 1865 the Capitol had been transformed from a sedate and self-contained building on a rather small scale to an exuberant and complex one of much greater size. Its breadth extended 751 feet across the brow of Capitol Hill and the feather-crested helmet of its corning statue, Freedom Triumphant in War and Peace, rose 287 feet, 5 and 1/2 inches above ground level.
Philadelphia architect Thomas U. Walter had won the competition in 1851 for the Capitol's extension. He and others presented designs based on three possibilities: making a square Capitol by building an addition on the east, placing new wings directly against the north and south walls, or attaching lateral wings to the old building via corridors. The latter, sanctioned by the Senate Committee on Public Buildings, maintained much of the original Capitol integrity.
The new rectangular chambers were placed in the center of each wing at the suggestion of Captain Montgomery C. Meigs (1816-1892) of the Army Corps of Engineers. In 1853 Meigs was put in charge of operations. Until 1859 he chose the painters and sculptors who decorated the Capitol Extension, suggesting themes to them that expressed Euro-American dominance of the continent. Italian-born fresco painter Constantino Brumidi (1805-1880) spent twenty-five years decorating walls and ceilings of committee rooms, offices, and corridors, as well as the rotunda's frieze and canopy painting. His subjects ranged from a visual dictionary of American flora and fauna to American history primarily told through classical allegories.
