Crise urbaine à Berlin ?

Berlin is currently in the throes of an identity crisis, in which questions of town planning have a key role to play. With the fall of the Wall and the return of the city as capital, Berlin became Europe's leading urban development project. Spaces for construction and reconstruction seemed to be infinite, and Germany's thriving economy attracted international promoters and architects. Thirty years later, public opinion in Berlin is dominated by virulent debates concerning the reconstruction of Hohenzollern Castle and the redevelopment of Tempelhof airport, along with questions concerning the heritage of the old East Berlin. 

How can we explain these frictions regarding the urban memory of Berlin? What have urban planning policies done to prevent Berlin from finding itself in the same situation as other capitals, overrun by gentrification, its centre asphyxiated by a concentration of shops and offices, making it difficult for the city to evolve toward a 3.0 city that respects the new ecological emergencies?
