Smithsonian National Museum of American History

The Smithsonian National Museum of American History at 1300 Constitution Avenue NW in Washington, DC is the most comprehensive repository of American material culture in the world, holding over three million objects that document the full sweep of United States history from the colonial era to the present. Free and open daily as part of the Smithsonian network, the museum occupies a modernist building designed by Steinman, Cain and White that opened in 1964 and has been substantially renovated in subsequent decades.

The museum's organizing framework is thematic rather than strictly chronological, with permanent galleries exploring American democracy, popular culture, scientific and technological innovation, military history, and the diversity of American communities. The American Stories gallery on the first floor anchors the visit with a survey of iconic objects — from a fragment of Plymouth Rock and George Washington's sword to the ruby slippers from The Wizard of Oz and an original Kermit the Frog puppet — that collectively trace the arc of American experience across four centuries.

The centerpiece of the second floor is the Star-Spangled Banner, the 30-by-34-foot garrison flag that flew over Fort McHenry during the British bombardment of Baltimore in September 1814, inspiring Francis Scott Key to write the poem that became the national anthem. The flag is displayed in a climate-controlled gallery designed to protect its fragile linen and wool fabric while allowing visitors to observe the full artifact. The adjacent American Democracy gallery places the flag in context with documents and artifacts related to constitutional government, suffrage movements, and civil rights struggles from the 18th century to the present.

The collections span an extraordinary range: Julia Child's complete kitchen, transported in its entirety from her Cambridge home and fully restored; the Greensboro lunch counter from the 1960 Woolworth's civil rights sit-in; Thomas Edison's laboratory equipment; presidential inaugural gowns; and a section of the Berlin Wall. The transportation and technology galleries on the lower level include full-scale locomotives, an early Model T Ford, and exhibits on the evolution of American communications and computing. The museum's size — three floors covering hundreds of thousands of square feet — means a comprehensive visit requires a full day, and most visitors find that focusing on two or three galleries per trip produces the most rewarding experience.
