Old Main Post Office
Chicago, IL
Opened: 1921 / 1934 / 2019
Architects: Graham, Anderson, Probst, and White
The Old Main Post Office (433 West Van Buren) was designed by Graham, Anderson, Probst and White and built in 1921. A major expansion added nine floors between 1932 and 1934. Presumably, the facility was oriented around mail trains (it's built over railroad tracks just south of Union Station) and the Postal Service moved to a new truck-friendly facility in 1997. The structure was placed on the National Register of Historic Places in 2001. Congress Parkway passes through the base of the building.
The architecture firm Gensler was tapped by developer 601W to lead a $800 million renovation. with the facility reopening in October 2019 as premium office space with a host of amenities.
