Many researchers in the field of cultural heritage point to the justification of the use of extended reality to present digital heritage. Research studies, but mainly user reactions, have responded to experiences with extended reality with a positive response. Technological research in the field of extended reality is advancing rapidly. In this review, we will cover the current possibilities and trends of extended reality. Specifically, we will focus on the application in creating interactive multimedia exhibitions in museums and galleries and presenting 3D digital heritage. We believe the practical examples shown will be an inspiration for application developers, content creators, and exhibition curators. Awareness of the possibilities and limits of the current state of technological progress is an essential requirement for utilisation of the full potential of extended reality.
