During the dialogical tour through all the exhibition rooms, historical events and the exhibition objects are presented. The speakers adapt to the knowledge horizon, the living environment and the language skills of the participants. The exhibition shows various turning points in German history. The exhibition begins in 1989 with the Peaceful Revolution in the GDR and ends in 1848, always showing in reverse order what really happened at these turning points. However, another possibility is always shown and why this did not happen. Inclusive and interactive stations invite visitors to try out, touch and participate. There is room for questions and discussion.Translated with DeepL
