The work shows a process that starts from the digitization of cultural heritage and through analysis arrives at the subsequent diachronic holographic representation. The object of the study was the creation of two holograms of historical buildings: the church of St. Maria in Sovana with an interesting subsoil and the ruin of church of St. Francesco, attributed to Sangallo il Giovane in Pitigliano. However, the theoretical setting of the research is placed at due distance from the twin term. It has implications and meaning that are not matched by producing a digital copy, even a very high resolution one. The use of different cognitive technologies and the assembly of the various inputs in a digital model can never be defined as a twin of the original. Bearing in mind what has just been specified, the work was organized according to different levels of acquisition of cognitive data. Obtained from the survey and from historical studies the shape of the original state, a historical narrative interweaving of digital models has been created. The hologram is a three-dimensional and dynamic representation, which in the case of the church of San Francesco shows the reconstruction of the ancient architectural complex, visualizing the evolution of the studies of historical documents, up to the vision of today's ruin. For the church of S. Maria, the underground area is reconstructed through the geoelectric analysis of the subsoil and of the urban composition. Use of high detection technologies (GPR and HVNSR). The holographic of the artifact, promotes scientific divulgation and its dissemination sharing experience, it is not realized through device indeed, but thanks a holographic display
