<P> The Senate ( north ) wing was completed in 1800 . The Senate and House shared quarters in the north wing until a temporary wooden pavilion was erected on the future site of the House wing which served for a few years for the Representatives to meet in , until the House of Representatives ( south ) wing was finally completed in 1811 , with a covered wooden temporary walkway connecting the two wings with the Congressional chambers where the future center section with rotunda and dome would someday rise . However , the House of Representatives moved early into their House wing in 1807 . Though the Senate wing building was incomplete , the Capitol held its first session of the United States Congress with both chambers in session on November 17 , 1800 . The National Legislature was moved to Washington prematurely , at the urging of President John Adams , in hopes of securing enough Southern votes in the Electoral College to be re-elected for a second term as President . </P>
