Alexanderplatz 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.

The Nikolaiviertel is an old quarter of the German capital of Berlin, founded c. 1200. Together with nearby Cölln, they jointly make up Alt-Berlin, the reconstructed historical heart of the city. Located in the Mitte locality, it is five minutes away from Alexanderplatz.
