The Emperor Alexander I of Russia visited Berlin in 1805: in honor of his visit we the Berliners named one square of their city Alexanderplatz. Once a cattle market, Alexanderplatz became a major commercial centre with a public market at the end of the XIX century.
During the 1960s Alexanderplatz was enlarged as part of the German Democratic Republic projects. After the reunification the surrounding buildings underwent a consistent renovation that is still ongoing.
In 2007, the Alexa shopping mall with some 180 stores was inaugurated.
In Alexanderplatz area we also find some historic buildings such as the Red City hall (Rotes Rathaus), traditional seat of Berlin government.
