BERLIN, GERMANY - JUNE 18:  Young women speaking French walk past the entrance to an U-Bahn underground commuter train station at Alexanderplatz on June 18, 2014 in Berlin, Germany. Alexanderplatz, a crossing point of tourists, commuters, shoppers, lovers, artists, bums and petty criminals, was built from the rubble of World War II by the communist authorities of former East Germany and today is the nexus of the reunified city.
