Washington DC Metro architecture.
Metrorail was designed by Chicago architect Harry Weese, and is an example of late-20th century modern architecture. With its heavy use of concrete and the repetitive nature of its design motifs, it displays aspects of Brutalism, which in Washington is also illustrated by the FBI’s J. Edgar Hoover Building. Simultaneously, with its coffered groin and barrel vaults, it evokes Neoclassicism, arguably the closest thing to an “official” architectural style in Washington. Historic examples of Neoclassicism in Washington consist of the U.S. Department of the Treasury, by Robert Mills and others; the former U.S. Patent Office building (now the Smithsonian American Art Museum), also by Robert Mills and others; the White House, by James Hoban; and the Beaux-Arts Lincoln Memorial, by Henry Bacon. In 2007, the design of the vaulted Metrorail stations was voted #106 on the list of America’s Favorite Architecture, conducted by the American Institute of Architects in conjunction with Harris Interactive.
