The National Gallery of Art in the United States, free of charge, can not enter at 5:30 p.m. to enter security checks, if there is a backpack, one-sided back, which is quite large, there are several floors, the biggest bright spot is the classical art here, you can see the real Van Gogh Monet, the most surprising is to see Van Gogh self-portrait, as well as Napoleon's portrait, of course, the first floor. The sculpture can not be missed, it is really quite beautiful. The art of sculpture is subdued to the veil. If you have time, you can soak for a whole day, but because the time is relatively short, you will go out in about an hour.
