This introductory article outlines the meanings behind and the reasons for suggesting “religious hotspots” as a new analytical concept in the study of religion. The idea of suggesting this concept is not to replace others – for instance, a pilgrimage site, a religious place, a supernatural place, or a storied place – but to broaden the perspective and to emphasize the dynamic, multidimensional, and relational aspects of place, not least concerning how a religious place can be a hotspot for some and a cold one for others, but also how a place can change from being a hotspot to a cold spot and vice versa. Being a heated place, a religious hotspot can also have an unintended effect on people being there. They can either become “infected” by or “cured” of a feeling of religious or spiritual belonging. The concept is a contribution to the growing interest in space and place when analyzing religion, in recognition of how a landscape or a particular religiously legitimized site can be an important element in collective cultural, social, and political meaning-making.
