Focus on this artwork and analyze the East Front extension.
The Capitol's East Front was extended between 1958 and 1962. A new exterior wall was built 32.5 feet east of the old exterior wall, and the space between them became the Main Lobby, offices and the East Extension Corridor. The Columbus Doors were moved from their original location to their present location, within the new exterior wall, in 1961 following the extension of the East Front of the Capitol.
