American Federal architecture typically uses plain surfaces with attenuated detail, usually isolated in panels, tablets, and friezes. It also had a flatter, smoother façade and rarely used pilasters. It was most influenced by the interpretation of ancient Roman architecture, fashionable after the unearthing of Pompeii and Herculaneum. The bald eagle was a common symbol used in this style, with the ellipse a frequent architectural motif.
The classicizing manner of constructions and town planning undertaken by the federal government was expressed in early federal projects of lighthouses, harbor buildings, universities, and hospitals. It can be seen in the rationalizing, urbanistic layout of L'Enfant Plan of Washington and in the Commissioners' Plan of 1811 in New York.2 The historic eastern part of Bleecker Street in New York, between Broadway and the Bowery, is home to Federal-style row houses at 7 to 13 and 21 to 25 Bleecker Street. The classicizing style of Federal architecture can especially be seen in the quintessential New England meeting house, with their lofty and complex towers by architects such as Lavius Fillmore and Asher Benjamin.3
This American neoclassical high style was the idiom of America's first professional architects, such as Charles Bulfinch and Minard Lafever. Robert Adam and James Adam were leading influences through their books.4
In Salem, Massachusetts, there are numerous examples of American colonial architecture and Federal architecture in two historic districts: Chestnut Street District, which is part of the Samuel McIntire Historic District containing 407 buildings, and the Salem Maritime National Historic Site, consisting of 12 historic structures and about 9 acres (4 ha) of land along the waterfront.
Modern reassessment of the American architecture of the Federal period began with Fiske Kimball.5
