The nation’s capital may boast
iconic architecture, featured on every denomination of American currency from the five dollar bill on up, but the real sights to see when visiting are found inside Washington DC Museums. The line-up of institutions here includes some of the best in the world, from the
National Gallery of Art to the National Museum of Natural History. Both can be found on the National Mall, along with other Smithsonian Museums dedicated to everything from American history to the science of air and space. The city, however, holds other hidden gems as well, including the ever popular
International Spy Museum, where visitors can delve into the history of the "second oldest profession" from angles both historical and fictional.
