Rupestrian Architecture is a particular form of architecture that presents ‘constructive’ and morphological characteristics different from the traditional ones. This volume proposes a general revision of procedures for the 3D acquisition, elaboration and representation of Rupestrian Architecture through a methodological study on the different phases of the process and a systematization of the operational criteria. The study was implemented by integrating different survey methods and, at the same time, by comparing software tools for data management and processing, focusing on the final representation and communication of the data. The methodological research was conducted as a national case study, represented by the Benedictine Monastery of Subiaco, an example of the integration of architecture and natural cavities that has allowed the author to find alternative solutions in fundamental aspects of the research.
