The United States Capitol, also known as the Capitol Building, is the meeting place of the United States Congress and the seat of the legislative branch of the U.S. federal government. It is located on Capitol Hill at the eastern end of the National Mall in Washington, D.C. It has fallen off the center of the federal district, but it is still used as the origin point for the street numbering system and as the center of the four quadrants.
This structure was built over 200 years ago. The first half of the structure was entirely destroyed during the 1814 burning of Washington, and was then rebuilt in five years. A few years after its completion, the building was further expanded by the addition of a massive dome, as well as the extension of the south wing to include a bicameral legislature (the House of Representatives in the south wing and the Senate in the north wing). The Capitol building resembles the two principal buildings of the executive and judicial branches, as it is constructed in the neoclassical style and has a white exterior. For formal purposes, the east and west elevations of the building are referred to as fronts, although only the east front was intended for the reception of visitors and dignitaries.
