The phenomenon of churching (attendance at churches outside parishes of residence) is associated with socio-economic and cultural transformations of society, including general growth of mobility. In this paper titular issue was described against the background of the concept of the life of a city and according to the concept of place. On the ground of the data gained, the presence of churching in the Old Town area in Poznań and its dimensions were primarily proved. This work is an introduction to an empirical research, concerning spatial behaviour of churching people and possible impact of their decisions on city centre functions.
