Implementing VR Techniques for identifying the Authenticity Levels of a Monument

Abstract. This paper presents a methodology for the virtual reconstruction of an archaeological site through the application of contemporary digital technologies. The research focuses on the systematic identification, evaluation, and representation of authenticity in virtual archaeological reconstructions, aiming to produce models that are scientifically founded and visually informative, while minimizing speculative or purely aesthetic interventions. Authenticity is critically examined as a theoretical construct to establish the conceptual framework of the study, with particular emphasis on transparency and user-oriented interpretative clarity as key criteria for its preservation in digital environments. The main contribution of this research is a workflow for evidence-based virtual reconstructions derived from archaeological data, bibliographic sources and historical documentation, by means of a classification of reconstruction according to distinct levels of authenticity. These levels are explicitly communicated through a Virtual Reality (VR) application using a structured colour-coding system linked to the underlying evidential sources. The development pipeline of the VR application is described in detail, enabling immersive, interactive exploration of the reconstructed site while maintaining a clear correspondence between visual representation and source reliability. The resulting system is evaluated in terms of methodological reliability, interpretative transparency, and usability, and directions for future enhancements and refinements of the VR application are discussed.
