German Culture, Digitally

Online German-related activities for this time of social distancing
During these strange and trying times, the Waterloo Centre for German Studies will continue to support research into all aspects of the German-speaking world. Further, we remain committed to supporting German-related cultural programming for the university and our wider communities. To this end, we have gathered a listing of different online activities, events, and courses that may be of interest to those curious about German culture and language.

We may from time to time update this list. The date of the latest update will be noted here: 03 December 2020.
