Berlin

From 1961 the city was divided by the Berlin Wall. Iron curtain formed a "Liberty Island" - a capitalistic microstate in the middle of a communist city. A barrier built overnight, represented a physical form of an ideological conflict, it was a state frontier and a plane wall, separating a family members from each other.
One of the significant frontier crossings between the East and the West was the "Glienicker Brücke" - the bridge over the river Havel. From the end of the WW II also known as the "Brücke der Einheit" - "The Bridge of Unity" - it connected West Berlin with Potsdam. The state frontier was in the middle of the bridge. For its strategic positioning, it was used for exchange of agents and in the ´80s the biggest after war hostage exchange among the world powers took place here.
