The United States Capitol is the home of the United States Congress and the seat of the authoritative branch of the U.S. government. It sits on Capitol Hill at the eastern end of the National Mall in Washington, D.C. In spite of the fact that not at the geographic focal point of the Federal District, the Capitol frames the starting point for the District's road numbering framework and the District's four quadrants.
The first building was finished in 1800 and was in this manner extended, especially with the expansion of the gigantic arch, and extended chambers for the bicameral council. Like the essential structures of the official and legal branches, the Capitol is worked in a particular neoclassical style and has a white outside.
