From Post Office to Postal Museum
Washington, D.C.'s Main Post Office
For 72 years this historic building was the main post office of the District of Columbia.
Since 1993 this building has housed the Smithsonian's National Postal Museum. Before that, it was the Washington City Post Office, built next to Union Station to speed the movement of incoming and outgoing mail.
Picture the lobby filled with people buying stamps, checking mailboxes, and socializing—in a time when mail was the primary means of communication.
The lower level once bustled with Washington, D.C. postal workers sorting mail for local delivery.
Today, much of the museum's vast collection is housed in the lower level.
