Old Executive Office Building

The Old Executive Office Building, formerly known as the State, War, and Navy Building, is on 17th St. right by the White House. It houses the offices of the Vice President and many of the White House executive staff.
It is a massive building in the French Second Empire style, built between 1871 and 1888. It was designed by Alfred B. Mullett, the Supervising Architect for federal buildings, and the elaborate style is in contrast to the classical Treasury Department on the other side of the White House. The exterior is granite with slate and cast iron. When it was built, it was the largest office building in D.C., with almost two miles of interior corridors.
This set of doors is from the facade on Pennsylvania Avenue.
