The Newseum blends high-tech with historical in a 250,000-square-foot museum of news. It offers visitors an experience that blends five centuries of news history with up-to-the-second technology and hands-on exhibits. The exterior’s unique architectural features include a 74-foot-high marble engraving of the First Amendment and an immense front wall of glass through which passers-by can watch the museum fulfill its mission of educating the public about the value of a free press in a free society and telling the stories of the world’s important events in unique and engaging ways. The Newseum features seven levels of galleries, theaters, retail spaces and visitor services. It offers a unique environment that takes museumgoers behind the scenes to experience how and why news is made.
