Vienna has always been a place where different cultures and religions come together. Situated at the crossroads between Eastern and Western Europe and the former capital of the multi-ethnic Habsburg Empire, Vienna has a long and rich religious history. It has been marked by contacts between a Roman Catholic majority and Protestantism, Judaism and, relatively early on, Islam. Since the end of the Second World War, Vienna has been characterised by processes of religious diversification through migration and progressive secularisation, which have shaped the city's identity. The Vienna Doctoral School of Theology and Religious Studies VDTR has produced an audio guide that explores the historical and contemporary religious characteristics of Vienna. The city tour invites visitors to learn about Vienna's religious history and present through the themes currently being researched in the theological and religious studies disciplines at the University of Vienna.
