The most famous example of Neoclassical architecture in the United States is likely Thomas Jefferson's Monticello in Virginia.

Form and balance dominate the Neoclassical style. "There is a purity of symmetry. These homes rarely stray from the Golden Section," explains Alan Cobb, vice president at Albert Kahn Associates in Detroit, Mich., referring to the Greek rule of proportion used in art and architecture.

Monticello, which took nearly 40 years to build, demonstrates symmetry on a grand scale. A circular entrance hall marks the center of the home, and is balanced by the large windows on either side. A fan-shaped window decorates the pedimented dormer -- another sure sign of Neoclassical style.
