Many cultural events are an adoption of past rituals and traditional customs created by destination managers in order to advance tourism development. However, to be successful, such cultural events need to be authentic and need the support of the local community and the capacity of the locals to identify themselves with what is staged. In this article, the authors analyze the perception of authenticity by tourists and local residents at Christmas Markets in Northern Italy. The main objectives of this article are to determine the level of authenticity perceived by visitors and to examine any differences between tourists and local residents. To do so, a logistic regression model was employed. The results show not only a difference between the two groups, but especially the need for local organizers to focus on the involvement of local residents in the organization of fringe events based on deeply rooted local customs. This will provide tourists with a broader experience of the local traditions and more opportunities to interact with local residents.
