The founding philosophy of many cultural events established after the Second World War was to enhance the dynamics of peace through supporting and developing multicultural understanding. Over 50 years after their establishment, this chapter investigates the potential of such iconic events to achieve this aim and contribute to the concept of peace through tourism, based on a longitudinal ethnographic case study of Llangollen International Musical Eisteddfod. The results show that this aim can be achieved by such events if they provide enough time and space for participants (performers and audiences) to interact. However, the study also identifies current cultural, political, and fiscal challenges in providing these temporal and physical spaces.
