Main article: United States Capitol rotunda See also: United States Capitol Subway System

The Capitol building is marked by its central dome above a rotunda and two wings, one for each chamber of Congress: the north wing is the Senate chamber and the south wing is the House of Representatives chamber. Above these chambers are galleries where visitors can watch the Senate and House of Representatives. It is an example of the neoclassical architecture style. The statue on top of the dome is the Statue of Freedom.

Underground tunnels and a private subway connect the main Capitol building with each of the Congressional office buildings in the surrounding complex. All rooms in the Capitol are designated as either S (for Senate) or H (for House), depending on whether they are north (Senate) or south (House) of the Rotunda. Additionally, all addresses in Washington, D.C. are designated NE, NW, SE, or SW, in relation to the Rotunda. Since the Capitol Rotunda is not located in the center of the District—it is slightly farther east and south—the four D.C. quadrants are not the same shape and size.
