Alexanderplatz

the largest, and arguably one of the most famous squares in Berlin. It historically had markets so was an important square for many centuries. In World War II, almost all of the area was bombed but it has been beautifully restored. All public transport lines now have stops here and the TV tower rises up from the center. The Fernsehturm (or TV asparagus, as the Berliners call it) is 368m tall and has a revolving café at the top. If it is a clear day, it is worth paying the €6 admission to see Berlin from up there.
