The rebirth of the historic Potsdamer Platz was Europe's biggest building project in the 1990s, a showcase of urban renewal masterminded by such top international architects as Renzo Piano and Helmut Jahn. An entire city quarter sprouted on terrain once bifurcated by the Berlin Wall and today houses offices, theatres and cinemas, hotels, apartments and museums. Highlights include the glass-tented Sony Center and the Panoramapunkt observation deck.
