Emerging Academic Research on the Integration of Virtual Reality Technologies in Heritage and Legacy: Bibliometric Analysis

The increasing integration of Virtual Reality (VR) technologies in cultural and historical contexts has significantly transformed the way heritage and legacy are preserved, studied, and experienced. This study provides a bibliometric analysis of the current research landscape surrounding the use of VR in heritage and legacy research. The results obtained highlight a research environment dominated by European institutions—primarily Italian and Spanish—complemented by Asian and French contributions that demonstrate a trend toward progressive internationalization. This field of research combines immersive technologies, photogrammetry for 3D digitization and user-centered designs, moving from conservationist approaches to holistic approaches that prioritize accessibility, educational dissemination and tourism. The results reveal a duality between digital documentation and immersive experience, while, among the countries with the most World Heritage sites, Italy leads in terms of quantity and average citations, China in terms of total volume, and Spain shows underutilized bibliometric potential despite its rich historical heritage. This analysis aims to trace the evolution of this field of research, uncover gaps, and suggest directions for future work that leverages virtual reality to safeguard and disseminate cultural heritage in an immersive and impactful way.
