Construction of the U.S. Capitol began in 1793 and has been "completed" several times. The original building was finished in 1826. The growth of the Congress compelled its expansion in the middle of the 19th century; the extensions and new dome were finished in 1868. An addition to the east front in 1958-1962 added more rooms to the Capitol. The restoration of the west front and terraces and the in-filling of courtyards, was completed in 1993. The most recent, and largest ever, addition to the Capitol, the Capitol Visitor Center, was completed in 2008.
