It documents a time when tight borders ran through Germany and separated eastern from western Europe and how millions of people in former East Germany (GDR), Poland, Hungary and other Eastern European countries fought for freedom and democracy in 1989. The exhibition targets a young audience, which is why it was first presented in Berlin's Heinrich-Hertz secondary school. Students had done additional research on the exhibits documenting the history of the Cold War, which their parents or grandparents experienced firsthand.
