The tourism-religion, a biome insufficiently studied, is often a confusion between religious tourism and pilgrimage, being seen as a spiritual phenomenon that involves a certain level of culture meant to motivate the initiation path of the believers. As the contemporary world is in a constant confessional transformation it is necessary the concept of ecumenical tourism, which is a complex phenomenon that is based on the theological principle “ut unum sint” (that all may be one), the return to Christian unity from a beginning. Applying the theoretical model DSPIR (EEA, 2011, F. Kineast, WSL, 2012) which describes the interactions between contemporary society and religious landscape, we can value and enhance optimally the information about the religious patrimony of the Archdiocese of Lower Danube.
