Central sections of the present building were completed in 1800. These were partly destroyed in the 1814 Burning of Washington, then were fully restored within five years. The building was enlarged in the 1850s by extending the wings for the chambers for the bicameral legislature, the House of Representatives in the south wing and the Senate in the north wing. The massive dome was completed around 1866 just after the American Civil War. Like the principal buildings of the executive and judicial branches, the Capitol is built in a neoclassical style and has a white exterior. Both its east and west elevations are formally referred to as fronts, although only the east front was intended for the reception of visitors and dignitaries.
