In our time, new technologies are progressively more and more approaching the cultural heritage's world. The opportunity to obtain – quickly and in a non-invasive way – virtual models of ancient sites, monuments and objects, using data taken by photo-modelling, digital photogrammetry or laser scanning techniques, offers new possibilities for their proper documentation, monitoring, physical conservation, restoration, archiving and valorization. Moreover, reverse engineering techniques allow a deeper understanding of architectural artefacts and collections by increasing their communication, display and interpretation. By showing a number of experiences related to the rich and famous archaeological heritage of Sicily Island, this paper intends to highlight how the use of new digital equipment and methodologies can be of great benefit for its safeguarding, representation, promotion and enjoyment.
