Augmented Reality in the Digital Preservation of Cultural Heritage: Case Study in Poland

Abstract: The integration of augmented reality (AR) technologies into heritage preservation is revolutionizing how to document, interpret, and engage with historical sites. This study presents an innovative approach that combines multiple data sources—including images, point clouds, and building information modelling (BIM) models—into a cohesive digital framework. Using the Unity platform, the data are integrated to provide maintenance recommendations and renovation strategies tailored to the unique needs of cultural heritage. The results are deployed in AR environment for immersive exploration and practical application in a Polish case, highlighting the transformative potential of AR in the digital preservation of heritage buildings.
