One of the best things about Washington, D.C. is the huge number of fantastic and usually free museums. Although one could easily spend more than a week perusing the best-known museums on the Mall, like the Air and Space Museum, American and Natural History Museums and the new African American History Museum, those wishing to see more have many options. In addition to The National Gallery, the artistically inclined should consider logging some hours at the Smithsonian American Art Museum and its White House-adjacent cousin the Renwick Gallery. Fans of modern art in particular will love the Phillips Collection and the Hirshhorn Museum (and its accompanying sculpture garden).
Visitors less fussed about spending time in art galleries will find numerous excellent museums addressing a variety of other topics. The United States Holocaust Memorial Museum provides a gritty and deeply moving look at one of history’s darkest chapters and the forces of hate that can lead to genocide. The National Museum of the American Indian showcases past and present native cultures of the Western Hemisphere, while the International Spy Museum provides an interesting and fun look at the historical and modern-day role of espionage. The National Building Museum, itself housed in the historically-relevant Pension Building, provides a fascinating look at architecture, construction, and urban planning. The Kennedy Center, though not strictly a museum, serves both as a monument to President John F. Kennedy and a venue for the performing arts.
