The combination of extended reality (XR) technology, which includes virtual reality (VR), augmented reality (AR), and mixed reality (MR), with cultural heritage studies has received deep attention from people in this field. This bibliometric analysis is instrumental and faster in making digital copies of heritage objects, reconstructing heritage places, and creating accurate digital copies close to reality. The idea clusters in this work center around digital legacy objects, virtual reconstructions, and times of use of mixed objects, highlighting the key points for people who are looking at in their studies. This work also maps out the current research, pointing to key researchers and key works. The findings open the door to new approaches such as superior blending with objects and presence in AR uses, creating enhanced virtual places, and blending AR with other technologies.
