Postal Square Building

The Postal Square Building is a four-story limestone and marble structure with granite columns and classical details arranged in balanced patterns across its facade. Today it houses both a museum with postal collections and offices for federal agencies.

Architect Daniel Burnham designed and completed the building in 1914 as Washington D.C.'s main post office and it served that function continuously until 1986. After that, the structure was repurposed to house a museum dedicated to postal history.

Inside, thousands of stamps and postal objects tell the story of how Americans communicated across distances and time. The collection shows the tools and methods that connected people before emails and phones existed.

The building is easily accessible by public transit with several metro stations nearby in northeast Washington D.C. Set aside enough time to explore both the museum exhibits and the historic spaces within the structure.

A working post office still operates inside the building and continues its original purpose while the space functions as a federal museum. This makes it one of the few places where you can see history living alongside everyday services.
