We will have several disciplinary sessions. In each session, researchers from one discipline will present and discuss projects and papers. This guarantees a profound, disciplinary exchange and discourse. However, disciplinary sessions will not take the whole day so participants will be able to attend several sessions from different disciplines. This enables a fruitful interdisciplinary exchange.

Our evening event will take place at “Die Küche”. The restaurant/bistro offers great food and a fantastic view over a harbor. Here, you get the best feeling of the industrial romanticism that Mannheim has to offer ;-)

DIE KÜCHE Jungbusch
5th Floor of “Musikpark” building
Hafenstraße 49
68159 Mannheim

How to get there

In case of good weather, the dinner venue can be reached by walking (see the following map).

In case of rain, bus no. RNV 60 is recommended. The bus starts every 20 minutes at the bus stop “Universität” next to the Mannheim palace and stops at “Popakademie”.

Departure bus stop “Universität”: 18:23, 18:43, 19:08

After the conference dinner ...

The restaurant/bistro “Die Küche” is in the heart of “Jungbusch” – a popular district in Mannheim for night owls. After dinner, there are plenty of possibilities to get a nice beer or cocktail. Some recommendable places are the Taproom, to get craft beer, the Hagenstolz or Kaprowbar for great cocktails and a lively atmosphere and the Sailer & Sieferle, a small bar (and barber shop) where you have to ring the bell and can only get in when there is enough space left. As such, it is a good place for an intense discussion on some of the insights that you have gained during the day… You find a more “rustic” (and not smoke-free!!) atmosphere in the Blau or the Rhodos – two real “institutions” in Mannheim.


Public transportation: The surrounding neighborhood is not dangerous per se, but getting to the next public transportation stop (“MVV Hochhaus”  or “Marktplatz”) is a 10 minutes walk you should do in small groups.

Taxi: +49-621-21818 or +49-621-44 40 44
