The building itself is a piece of art. Truly worth of spending the time here, walking looking. A lot of very interesting portraits and pieces of art.
Visit Newseum
This “newseum” is dedicated to the First Amendment and contains everything imaginable regarding the right to freedom of the press from the Federalist Papers to the Internet and everything in between (newspaper, radio, TV).
Visit United States Holocaust Memorial Museum
Plan on spending a few hours at this museum. Four floors full of fascinating history of the holocaust. Lots of film footage as well as displays.
