The Capitol complex includes three major office buildings and one annex building for the House of Representatives and three major office buildings for the Senate. (A map of the U.S. Capitol complex [112k] and an aerial photograph [50k] showing the locations of the congressional office buildings are available.) Although several of these buildings were named long after their construction and occupancy, their present names are used here.

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 (585,532 square feet) 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.
