"The Wall Park, where the borderline between East and West splitted the city in two pieces from 1961-1989 functions as a gathering place for the younger generation before night clubbing"

Done by the organization Urban Dialogues:
The non-profit art organization metropolitan urban
dialogues is treating questions of urban change and
