The most modern of the House buildings, the Rayburn Building, was opened in 1965.

Over the years, two other buildings were acquired for office space by the House of Representatives. The Congressional Hotel on C Street, obtained in 1972, was subsequently named for former Speaker Thomas P. O'Neill, Jr.; it was demolished in 2002. In 1975 a building located at Second and D Streets originally built for the Federal Bureau of Investigation was acquired; it was subsequently named for former Minority Leader Gerald R. Ford.

The National Garden, a new U.S. Botanic Garden facility that will be located on three acres west of the Conservatory site, will be a showcase for unusual, useful, and ornamental plants that grow well in the mid-Atlantic region. It will also provide "living laboratories" for environmental, horticultural, and botanical education....

Originally a wooded wilderness, the U.S. Capitol Grounds today provide a park-like setting for the Nation's Capitol, offering a picturesque counterpoint to the building's formal architecture.

The Capitol Visitor Center, which will be built underground adjacent to the Capitol's east front, will contain exhibits, orientation displays, theaters, and other facilities to make the visitor's experience in the Capitol more informative and meaningful. It will also make the U.S. Capitol more accessible and secure.

Their subjects include prominent Americans, important moments in history, and allegorical representations of the nation's ideals.
