Berlin Alexanderplatz was named in honor of a visit of the Russian Emperor. Alexander I to Berlin on 25 October 1805 The square gained a prominent role in the late 19th century. Its heyday was in the 1920s, when it was at the heart of Berlin’s nightlife.
Alexanderplatz became GDR territory in 1961 and was turned into a pedestrian zone and was surrounded by several notable structures including the ‘Fernsehturm' (TV Tower).
During the peaceful Revolution of 1989, the Alexanderplatz demonstration on 4 November was the largest demonstration in the history of East Germany. Ever since the German reunification, Alexanderplatz has undergone a gradual process of change with many of the surrounding buildings being renovated but it still has retained its socialist character.
Nowadays no emperors on the square but lots of homeless.
