Mapping Sacred Spaces - The Digital Archive Project
The Digital Archive Project represents a fundamental step of the project Mapping Sacred Spaces. Forms, Functions, and Aesthetics in Medieval Southern Italy, directed by Tanja Michalsky, Elisabetta Scirocco, Ruggero Longo (Bibliotheca Hertziana – Max Planck Institute for Art History) and Manuela Gianandrea (Università di Roma "La Sapienza"). This project aims to fully analyze the sacred space in the Middle Ages in Southern Italy between the tenth and fourteenth centuries.
