In the 1970s, two more buildings became available for the House: the former Congressional Hotel, the O'Neill House Office Building (demolished in 2002), and a larger building originally constructed for the Federal Bureau of Investigation (now the Ford House Office Building). A third building for the Library of Congress, the James Madison Memorial Building, opened in 1980 and the Senate's third building, the Hart Senate Office Building, was occupied in 1982. The most recent large structure within the Capitol complex is the Thurgood Marshall Federal Judiciary Building, which was opened in 1992.
