Berlin was divided by an insurmountable Wall for more than 28 years. The border between the democratic West and the communist East cut right through the city center. The renowned journalist Christian Bahr recounts the history of the Berlin Wall and guides us to the places where the time of division is still remembered. The voices of eyewitnesses bring to life what it was like to live in Berlin at that time, to attempt an escape or witness the Wall coming down. Excerpts from important speeches underscore the international significance of these events. Ten tours along the former border take us to the sites where history happened and where traces of the Wall have been left behind.
