Learn About the US Capitol BuildingWhen French engineer Pierre Charles L'Enfant planned the new city of Washington, he was expected to design the Capitol. But L'Enfant refused to submit plans and would not yield the authority of the Commissioners. L'Enfant was dismissed and Secretary of State Thomas Jefferson proposed a public competition.
Most of the designers who entered the competition and submitted plans for the U.S. Capitol were inspired by Renaissance ideas. However, three entries were modeled after ancient classical buildings. Thomas Jefferson favored the classical plans, and suggested that the Capitol should resemble the Roman Pantheon with a circular domed rotunda.
Burned by British troops in 1814, the Capitol went through several major renovations. Like many buildings constructed during the founding of Washington DC, most of the labor was done by African Americans - some paid, and some slaves.
The most famous feature of the US Capitol, the cast-iron Neoclassical dome by Thomas Ustick Walter, was not added until the mid-1800s. The original dome by Charles Bulfinch was smaller and made of wood and copper.
