In the location's words:

The Berlin Dungeon takes you on a journey through 800 years of Berlin's dark history. Professional actors bring the eerily "amusing" figures of Berlin's dangerous past back to life in 360° settings. Escape the curse of the witch Catarina Selchow, wander through the labyrinth of the Hohenzollern and meet Berlin's most notorious serial killer Carl Großmann. Face Berlin's only indoor freefall tower, Exitus, and plunge 12 meters into absolute darkness. Are you brave enough?
