The United States Capitol is the seat of the United States Congress, the legislative branch of the federal government. It stands on Capitol Hill at the eastern end of the National Mall in Washington, D.C., and forms the origin point for the street numbering of the district and its four quadrants. Like the main buildings of the executive and judicial branches, it is built in a neoclassical style with a white exterior.

The central sections were completed in 1800, when the 6th Congress convened there. British forces partly destroyed the building in 1814, and it was fully restored within five years. Its wings were extended during the 19th century, with the House of Representatives in the south wing and the Senate in the north wing, and the massive dome was completed around 1866.
