As demands on city post offices changed, so did this building.
1911: Construction of the post office next to the new city train station begins.
1914: On September 14, the Washington City Post Office opens for business.
1935: The building is expanded with the help of Federal funds intended to boost the nation’s depressed economy.
1957-59: The post office is modernized to improve mail handling, communications, and customer service.
1971: A second burst of modernization, including Formica counters and a dropped ceiling, increases usability for visitors but covers much of the original architecture.
1986: To accommodate larger postal volumes, a mail processing plant is built two miles north. A scaled-down post office reopens downstairs.
1989: Renovation begins to make way for federal offices and the National Postal Museum.
