Abstract. This paper describes the results of a research that aimed to focus on a possible approach in the knowledge, representation and dissemination of the Cultural Heritage through CLOUD-to-BIM-to-VR application processes. Starting from reality-based surveys of the current state and information modelling in BIM platforms, the experimentation conducted involved the construction of a VR fruition system for the Simón Ruiz Hospital in Medina del Campo (Valladolid, Spain). An application for mobile devices was therefore designed to describe the artifact and the information acquired - or processed - during the various research phases according to alternative methods and completely independent from the software that generated them. The fruition system is completed with cardboard type supports, for stereoscopic viewing, and controller, to allow the user to navigate in the represented scene and activate the information hotspots that implement the contents of the App.

Specifically, the results presented here relate to the operational sequences and products obtained in the organization and programming of the App, structured to allow a multidimensional and multimodal fruition path. The characteristics that connote it, therefore, are related to the setting of incremental levels of knowledge, different by type of content displayed – historical, descriptive, technical, etc. –, form in which it is presented – spherical and photographic images, point cloud, geometric and informative model, textual descriptions, etc. – and integration of hotspots for extend the informative and descriptive content.
