The patrimonial rehabilitation process is configured in the contemporaneity as an exercise of synthesis in which the constructive, compositional, organoleptic, etc. process is systematically analyzed. These processes of decomposition are not usually evident when the realities on which we have to intervene are the result of continuous processes of transformation and historical sedimentation. To be able to undertake any approach to these elements or assemblies, we need the help of numerous tools. The result is a contextualized project in form and discourse, in which the photogrammetry, the muraria and structural restitution, the paramental reading, the existing bibliographical research and the drawing of connected and unconnected elements, together with stratification of archaeological graphic elements, etc. have configured a ‘unicum’ to determine an intervention tool, customized for this work and determined by the requirements of it.
