In order to allow for the installation of scaffolding and floor, statuary, and artwork protection in conjunction with the Dome Restoration Project, the Rotunda of the Capitol will be closed from Monday, July 27 through Monday, September 7. While the Rotunda is unavailable for tours, an alternate tour route will be provided. The Capitol Visitor Center is open during the closure of the Rotunda and will offer special activities which do not require advance reservations. You can also download our new U.S. Capitol Rotunda app.

The Campus Grows Again

The Legislative Reorganization Act of 1946 brought significant reforms in committee staffing and operations. These increased Congress’s need for hearing rooms and staff offices. Four new buildings helped to meet the demand: the Dirksen and Hart Senate Office Buildings (opened 1958 and 1982) and the Rayburn and Ford House Office Buildings (opened 1965 and acquired 1975).

The Library of Congress staff and collections also were expanding. Completed in 1981, the Madison Memorial Building (one of the world’s largest library structures) relieved space shortages and made possible the restoration of the Library’s Jefferson and Adams buildings. The underground Capitol Visitor Center, opened in 2008, covers about 580,000 square feet on three levels, giving Americans a more informative, comfortable, and secure way to visit their Capitol.
