In recent years, new innovations have been introduced into the cultural heritage sector, aimed at offering more engaging and accessible tours to the public. The article discusses the development process of the VirgilTell project, for the visit of inaccessible places in the Racconigi Castle, one of the Savoy residences in Piedmont (Italy), by the UXD Team of Politecnico di Torino. The places assigned to the project are being restored and therefore excluded from the tour. The VirgilTell experience aims to include and make them accessible to visitors, through a virtual tour including multimedia content for the entertainment and involvement of the users. The visit has been realised through mixed techniques between VR and AR for the narration of the spaces in which the user takes part in a journey made of narratives by characters from the past and objects that no longer exist. The VirgilTell visit was also created with the aim of anticipating, in promotional terms, the physical visit to the museum spaces undergoing restoration, so as to attract visitors back inside once the work is finished
