Ernst-Reuter Platz

The square is located on the major east-west axis of Berlin in the Berlin district of Charlottenburg-Wilmersdorf. It is located in the area of Campus Charlottenburg (science location: TU Berlin, University of the Arts, Physikalisch-Technische Bundesanstalt etc.) and in the area of City West.

Five roads lead to the large roundabout:

  • Straße des 17. Juni
  • Hardenbergstraße
  • Marchstraße
  • Otto-Suhr-Allee

The central island of the roundabout can be reached underground via the underground station. However, most visitors to the middle of the roundabout, which is bypassed by traffic, take the short path across the traffic lanes.
