Topography of Terror (Topographie des Terrors) is one of the most significant and visited memorial complexes in Berlin, Germany. This documentation center and open-air museum is located on the site where, from 1933 to 1945, the central organs of the Nazi apparatus of repression were situated: the headquarters of the Gestapo (Secret State Police), the SS, and the Reich Security Main Office. It was here that crimes committed across Europe were planned and coordinated.
The main goal of the museum is to clearly and documentarily tell the story of the rise and actions of the National Socialist regime. The permanent exhibition, housed in a building specifically constructed in 2010, covers more than 800 square meters. Through numerous photographs, documents, and multimedia materials, the exhibition details the structure of the institutions of terror and focuses not so much on the victims, but on the perpetrators and the management technologies based on fear.

In addition to the main indoor exhibition, the complex includes an outdoor section. Here, visitors can walk along the excavated remains of the Gestapo cellars, where the prison was located. The museum grounds are also crossed by the longest segment of the Berlin Wall remaining in the city center, which is a historical monument in its own right. Every year, more than a million people visit the Topography of Terror, making it an essential site for reflecting on the tragic pages of 20th-century history. Entry to the center is free.
