Leveraging extended reality technology, digital reconstruction, and reproduction of cultural heritage can enable effective solutions to enhance museum experience. Particularly, this paper focuses on virtual reality as a tool to support both onsite and online visits of a temporary exhibition dedicated to Raphael and Angelo Colocci. We present an immersive VR experience of the School of Athens. Within the digital reconstruction of its architecture, two actors provide descriptions of its features and significance, blurring the line between real and virtual. Furthermore, to ensure that visitors can continue to explore the exhibition even after its closure, we developed a virtual tour. Taking advantage of panoramic images and 3D digital replicas, it continues to convey the same cultural contents, preserving the essence of the exhibition. In conclusion, we conducted evaluations of both the experiences to assess their effectiveness and gather insights for further enhancements
