Once the headquarters of the Nazis’ secret state police called the SS, Topography of Terror is an indoor and outdoor museum that attracts more than 1 million visitors every year. It is an important historical site to visit, although it can be emotionally tough to experience the museum’s former prison cells and other exhibits.
Topography of Terror is recognized in Hoptale's First-Time Visitor Guides as one of the top things to do in Berlin.
