Around, above and below, visitors to the Great Hall of News are surrounded by a continuous flow of news. Instant, breaking, historic news that is uncensored, diverse and free.

This gallery tells the timeless story of news, of many voices struggling to be heard, and of the people and machines that spread that news.

News breaks, and a deadline is looming. Can you prepare a complete, timely and accurate report? The Interactive Newsroom gives visitors a chance to play the role of a reporter or photographer.

This gallery explores the horrendous events of Sept. 11, 2001, and the extraordinary challenges that faced the journalists trying to report the news to a shaken nation and world.

The Berlin Wall was strong enough to stop a tank, but it couldn't stop news from getting into East Germany by word of mouth, smuggled messages or radio and television.

Freedom has always been the key to open, enlightened societies. The books and documents in this display are some of the cornerstones of freedom.

More than 700 newspapers transmit their front pages electronically to the Newseum every day. Up to 80 are enlarged and printed for display in this gallery — among them one from every state and the District of Columbia as well as a sampling of international newspapers.

Journalists face danger every day. Some are targeted deliberately, while others simply are in the wrong place at the wrong time. They often take calculated risks, sometimes paying with their lives.

In this gallery the Newseum mounts exhibits that explore compelling topics and issues in more depth. Here are fresh takes on important news events, news-related anniversaries and emerging media trends.

This terrace offers a panoramic view of one of the most famous streets in the United States. The exhibit rail tells the rich history of the events that played a role in shaping Pennsylvania Avenue, the site of presidential parades and funeral processions, joyful celebrations and raucous demonstrations.

In the Ethics Center, interactive kiosks allow you to tackle real-life reporting dilemmas and see how journalists and other visitors responded. Or, you can challenge your friends to a fast-paced game on media ethics.
