3D documentation for archaeological conservation: some case studies in Central Sicily

Artificial cavities are tangible signs of past generations’ actions: a legacy that holds unique features because every wall, every vault, every recess obtained by material removing is an original and not repeatable piece. The study of these underground spaces requires a specific approach aimed at the recognition of their constructive singularities and should follow rigorous measurement procedures. In this sense, two activities, the one related to the Grotto of Saints in Enna, a space carved into the rock, showing frescoes from13th century BC and the other to the Necropolis of Realmese (9th-7th centuries BC) in Calascibetta, were conducted based on an integrated approach between traditional techniques and data capture technologies. Both sites represent an interesting field of study in terms of 3D data acquisition and investigation aimed at drawing up conservation and valorisation projects able to give back to the community these important witnesses of civilization and culture.
