In page Alexanderplatz:

"

Ever since German reunification, Alexanderplatz has undergone a gradual process of change with many of the surrounding buildings being renovated. After the political turnaround in the wake of the fall of the Berlin Wall, socialist urban planning and architecture of the 1970s no longer corresponded to the current ideas of an inner-city square. Investors demanded planning security for their construction projects. After initial discussions with the public, the goal quickly arose to reinstate Alexanderplatz's tram network for better connections to surrounding city quarters. In 1993, an urban planning ideas competition for architects took place to redesign the square and its surrounding area.[citation needed]
