Simply the greatest collection of American history artifacts in the world, the National Museum of American History is a part of the vast Smithsonian Institution. Located on The Mall in Washington, DC, the museum collects, preserves and displays American heritage in the areas of social, political, cultural, scientific and military history. Documenting the American experience from Colonial times to present, the museum looks at growth and change in the United States.
 
Note: The museum is under renovation and closed until Summer 2008. However, a sizable portion of the exhibits is on display on the museum's website as well as on temporary display at the National Air and Space Museum.
