The U.S. Capitol dome towers above the Roman columns and manicured gardens of this iconic heart of American government. Topped by the bronze Statue of Freedom, the Capitol is the political and geographic center of Washington D.C. The building houses the legislative branch of Congress, with the Senate meeting in the north wing and the House of Representatives in the south wing. When Congress is in session, visitors can watch politicians debate all flavors of legislative issues, as they’ve done here since 1800.
