The city of St-Ursanne, located in the Swiss Jura, is a city with a rich historical and religious heritage. According to the legend, the town was founded in the VIth century by Saint Urscinius, an Irish monk. For the 1400th anniversary of the death of its death, the ecclesiastic township has created a steering committee to organize events and bring a new dynamic to the city. One part of the actions taken by the committee is to modernize the visit of the town through a location-based mobile app. The innovation of the project is to combine an access management system (Circuit Secret) with video-projection and Augmented Reality to provide a rich and original experience to the visitor of the city.
