The huge Potsdamer Platz has been a major focal point for Berliners since the 19th century, the busy meeting point of half a dozen major thoroughfares. Historically, the square was dominated by the enormous Potsdamer train terminal, and at the turn of the 20th century it was a major dining, hotel, entertainment and shopping hub. Potsdamer Platz was destroyed by Allied raids during World War II. Before reunification the barren area was a militarized no-go zone cut in two by the Berlin Wall; this no man’s land was one of the first areas to be breached in November 1989. Since the 1990s, Potsdamer Platz has undergone a total rebirth as the new heart and inspiring symbol of the reunified Berlin. Take in the surroundings from the Panorama Observation Deck, and seek out the only pre-WWII building, the Weinhaus Huth.
