The aim of this paper is to advance the theoretical discourse on the enhancement of cultural heritage in tourism by presenting an integrative framework for the development of immersive tourist experiences. Using the Templar heritage of Tomar as a case study, this research employs a qualitative methodological approach to identify and inventory tangible, intangible, and natural resources related to the Templars. Subsequently, the paper conceptualizes a mobile application using geolocation, augmented reality (AR), and artificial intelligence (AI). This application is designed to bring together all the catalogued Templar heritages in an interactive, gamified experience, thereby addressing the tourism management requirements of personalization and differentiation. A multi-disciplinary analysis incorporates historical, cultural, symbolic, and touristic perspectives, enriching the visitor's engagement with the Templar narrative. The final product is conceived as a tool for cultural preservation and as a strategic lever for strengthening the positioning of Tomar as a unique and exemplary Templar tourist destination.
