This paper presents the Virtual Museum of Sculpture (VMS) of Pietrasanta, a permanent Virtual Reality installation enabling users to interactively explore a museographical diffused virtual space. The virtual environment hosts several digital 3D models of sculptures realized by important Italian artists of the XX century, connected for historical and cultural reasons with the town of Pietrasanta, a renowned place near the marble quarries of Alpi Apuane. The VMS is currently being enriched of new content, aimed at promoting local art and culture, with the perspective of developing guidelines for an integrated methodology sharing museological and ICT know-hows, targeted to the design of specific virtual applications and to the qualitative evaluation of their social impact as a novel important means of communication and learning.
