We would like to invite you to the 20th International Congress of the IUSSI to Freiburg (Germany). It will be held from the 16th to the 20th of August, 2026.
Freiburg is a University City with around 230,000 inhabitants, known for its beautiful old town. It is located next to the Rhine valley in the southwestern part of Germany, next to the border of France and Switzerland. By plane, it can be reached via the Frankfurt International Airport or the Euro Airport Basel/Mulhouse/Freiburg with direct train connections to Freiburg.
Freiburg is one of the sunniest cities in Germany with a green ethos, surrounded by the nature of the Black Forest and the Rhine valley with its many vineyards. More information with be circulated later this year. We are looking forward to welcoming you!
