Throughout the last two decades 'interreligious dialogue (IRD)' has become a significant research-topic for the Academic Study of Religion. In most cases, the respective analyses focus on a variety of different contact-formats among individuals and/or institutions that are explicitly framed in religious terms. They tend to neglect, however, the fact that most contacts among religious individuals and/or institutions take place in secular spaces - from supermarkets up to parliaments. The paper will draw from data collected for an oral history project on religious plurality in inter-war Vienna. It will have a look at the school as a secular space of contact among religions.
