Alexanderplatz (German: [alɛkˈsandɐˌplats] , Alexander Square) is a large public square and transport hub in the central Mitte district of Berlin. The square is named after the Russian Tsar Alexander I, which also denotes the larger neighbourhood stretching from Mollstraße in the north-east to Spandauer Straße and the Rotes Rathaus in the south-west. Alexanderplatz is reputedly the most visited area of Berlin, beating Friedrichstrasse and City West.
