Tourism scholars and players of the sector alike are very interested in the motivations for the tourist’s journey, as they influence the demand—with regard to the choice of the destination and the organization of the trip—and the offer—with regard to the definition of the tourism product. Religious tourism is an important area of the scientific debate on the motivation to travel; part of the literature clearly distinguishes the cultural and laical motivation of tourists (which can be considered religious tourism) from the desire to live an experience of faith (pilgrimage), while today, the orientation of scholars is to bring back under the label “religious” spiritual, religious, and cultural motivations. This study analyzes the case of the city of Pompeii, and it aims to investigate the possible synergy that could be created between the historical-cultural and religious interests of the city, identifying possible strategies for sustainable tourism. The study develops a quali-quantitative analysis of the reviews of the “Pontifical Sanctuary of the Blessed Virgin Mary of the Holy Rosary of Pompeii” on TripAdvisor and presents a content analysis on the most frequent words utilized by users to describe their touristic experience.
