How to get here?

Frankfurt is located very much in the center of Europe and there are trains from many European cities that get you to its main station (Frankfurt (Main) Hbf). You can also take a flight to Frankfurt Airport.

From Frankfurt Airport you can take S-Bahn line 8 (or 9) to get to get to Frankfurt (Main) Hbf. From Frankfurt's main train station you can take U-Bahn line 4 to its final stop, Bockenheimer Warte, which is where our campus is located.

Please note that the airport Frankfurt-Hahn is much further from Frankfurt and, due to a lack of convenient public transport options, we do not recommend that you use this airport to get to Frankfurt.
