Which Washington, D.C., museum opened its National Mall building on July 1, 1976, during the U.S. Bicentennial?

The National Air and Space Museum opened its National Mall building on July 1, 1976, during the U.S. Bicentennial.

The Smithsonian museum traces its institutional origins to the National Air Museum, established by Congress in 1946. Its major building on the National Mall was completed three decades later, opening during the intense public celebrations surrounding the Bicentennial.

The museum focuses on aviation, space exploration, planetary science, and related technology. Its collections include major artifacts such as the Apollo 11 command module Columbia, Charles Lindbergh’s Spirit of St. Louis, and the Wright Flyer.

The opening date can be confused with the museum’s founding date. The institution was established in 1946, but the prominent National Mall exhibition building opened in 1976, making it a notable Bicentennial-era landmark.
