Old Patent Office Building

The Old Patent Office Building is a government structure in downtown Washington, D.C., occupying an entire city block. Its Greek Revival design features soaring Corinthian columns, vast interior galleries, and balanced architectural proportions throughout.

Construction began in 1836 and continued through the Civil War era, with the building eventually serving as a military hospital during that conflict. It later became headquarters for the Patent Office and has remained a landmark documenting the nation's institutional history.

Two museums housed here display American paintings, sculptures, and portraits that reflect the nation's artistic heritage. Visitors wander through the galleries to encounter works that span different periods and artistic movements.

The building sits between F and G Streets and 7th and 9th Streets in the Chinatown neighborhood, making it accessible by public transportation. Plan for several hours to explore the galleries comfortably without feeling rushed through the collections.

Clara Barton worked here from 1854 to 1857, becoming the first female federal employee to earn equal pay alongside her male peers. Her tenure in these halls marked an early step toward gender equality in American government.
