German Spy Museum: German Spy Museum in Berlin gives a unique insight into the gloom of espionage right where the Wall once divided the city. The visitors are welcome to use the most recent multimedia-based technology to detect the bizarre and sneaky methods of agents and secret services.Potsdamer Platz : Potsdamer Platz is the most striking example of urban renewal that turned Berlin into the \\"New Berlin\\" in the 1990s although it is not typically a square. The area today consists of three developments known as the Daimler City (1998), the Sony Centre (2000) and the Beisheim Centre (2004), which literally transformed the dormant wasteland where the Berlin Wall stood between east and west Berlin until 1989.Transportation: The U5 metro line in the heart of Berlin now has a new section connecting Berlin's many cultural attractions between Alexanderplatz and the Brandenburg Gate. With three new stations, the line offers a convenient and exciting way to experience the city.The new international Berlin airport (BER) is also now open, a positive signal for improved international connections at a time that's so challenging for tourism and congress industry. As a modern hub for air traffic, the BER will connect Berlin in future with all Europe's main hub airports.25 TTW World
