It is important both for its individual design as a monumental public and light-industrial service building, and in its important complementary visual and functional relationship to Union Station and the U.S. Capital.
The post office was designed by the nationally recognized firm of D.H. Burnham and Company , which was noted for its major contributions to both architecture and the planning of many cities throughout the United States, especially for the role of its principal, Daniel Burnham, in the development of the Plan of 1901 for Washington, D.C.
The post office building is a critical element in the architectural and visual frame of the U.S. Capitol, including Columbus Plaza, which was developed s an extension of the 1901 Plan for Washington. The building was built as a national model of the U.S. Postal Service's highest standards of post office design, function, and service, and served as the main Washington City Post Office for 72 years.
Designed by architect Daniel Burnham, the City Post Office was built in 1914.
