Neoclassical architecture had an enormous influence on the archicture in the United States during the late-18th and early-19th Centuries. The Founding Fathers, particularly Thomas Jefferson, were heavily influenced by ancient Greece and Rome, and preferred architectural styles that reflected the archeological discoveries that had been taking place in those regions earlier in the century. Two of the most prominent examples of neoclassical architecture in this country are the United States Capitol and the White House, but the West Wing of the National Gallery of Art, the National Archives, and, not surprinslgy, the Thomas Jefferson memorial.
The prevalence of neoclassical architecture in the United States can be seen almost every state, not just in local federal buildings like post offices, but also in state government buildings, especially capitol buildings, and also in some major art museums, including the Philadelphia Museum of Art and the Art Institute of Chicago. Throughout the United States, one or more of the neoclassical styles of architecture can be found, whether "federal architecture," "breaux arts," "classical revival," or "Greek revival," all can be located in major cities in most states. The importance of ancient Greek political thought and of the wave of republicanism in ancient Rome were clear in both the drafting of key documents founding the United States, and in the manner in which major buildings would be designed.
