Tours of the historic Capitol Building begin at the orientation theaters with a 13-minute film, "Out of Many, One," which will take you on a journey through our country's struggle to establish the world's first truly representative democracy and introduce you to the magnificent building that houses our Congress.
U.S. residents can book a tour through the office of their Representative or Senator. Tours can also be arranged directly through the U.S. Capitol Visitor Center using the online reservation system.
