## 1 Introduction  
A noticeable trend is emerging in the evolution of conventional museum displays, marked by the incorporation of multisensory Extended Reality (XR) technologies. This category encompasses virtual reality (VR), augmented reality (AR), and mixed reality (MR), each adding a layer of immersive sensory experience to the traditional exhibition format [1]. Indeed, the use of XR technologies in cultural heritage is increasingly confirmed as positive [2]. Despite the current small number of publications on this topic \"the majority of the authors are developing VR experiences\" by resorting to game engine software. In fact, these types of technologies present \"clear benefits for attracting visitors and encouraging revisits\", enabling users to experience more engaging, immersive, and meaningful cultural heritage content [3]. Recent studies have shown that VR in museums not only enhances the visitor's experience by providing immersive and interactive learning opportunities but also serves as a powerful tool for storytelling and preservation of cultural heritage. For instance, [PERSON] et al. discovered that absorptive experiences in VR significantly influence the overall museum VR tour experience and visitor's intention to visit a museum, suggesting that VR can substantially enhance the educational and entertainment value of museum visits [4]. Furthermore, immersive VR applications in cultural heritage contexts have shifted the way individuals access and experience cultural assets, from virtual museum tours to exploring ancient buildings, thus broadening the reach and accessibility of cultural education [5]. These technologies not only augment the visitor's experience but also offer new methodologies for cultural heritage preservation and interpretation, enabling a richer and more detailed understanding of past civilizations and cultural narratives [6; 7]. The adoption of virtual exhibition spaces in the metaverse responds to the progress of cutting-edge technologies and the interest of museums in integrating them as a complementary activity to attract visitors, improve their relationship with them, and add value to their exhibits. Also, these virtual environments contribute to an immersive and accessible experience that provides new ways of interacting with culture. One of the key motivations behind adopting these technologies is their ability to transform the conventional museum experience. Virtual and augmented realities enable users to explore, learn, and interact in ways that go beyond traditional physical boundaries, making cultural heritage accessible to a global audience. This is particularly vital for providing educational and cultural access to remote or underserved populations, who can now experience world-class exhibits from the comfort of their own homes. The motivation also stems from the potential of these technologies to create engaging and dynamic environments. Such environments encourage users to interact not only with the exhibits but also with each other, promoting a sense of community and shared learning. Advanced technologies allow for the creation of interactive narratives and educational programs within the virtual space, enhancing the user's engagement and understanding of cultural heritage. Furthermore, the shift toward digital integration in museums reflects broader societal trends towards digitalization and virtual interaction. As digital literacy grows and virtual experiences become more common, museums are adapting to meet the expectations of a technologically adept audience. The adoption of immersive technologies is a strategic response to these trends, positioning museums as forward-thinking, inclusive, and adaptive institutions in the digital age. By embracing virtual and augmented realities, museums are not only expanding their reach but also redefining the possibilities of cultural engagement and education, ensuring they remain relevant and resonant in an increasingly digital world.
