## 5 Conclusions  
The proposed methodology is divided into two phases. The first phase is data collection and the generation of a physical twin. Note that this first phase has been extensively developed in other bibliographies that are cited during the text, and in other publications of the research group to which we refer. Regarding the first phase, we state that:  
* First of all, as a society, we have the obligation to digitize the world in which we live in order to preserve it as a digital twin for future generations: a database of the present. * Secondly, we have the opportunity to recreate from these digital twins lost architectural environments and future digital environments: foundations of the past and the future. * There are many digitization methods, each with its advantages and disadvantages [4; 17; 26; 56; 57; 58]. In the present study, a low-cost methodology based on the use of UAVs has been chosen [8; 59], which has been outlined and incorporated into the workflow. This scheme is supported by other works and the professional experience of the authors [1; 25]. * For some time now, new representation technologies have allowed us to create resources and content that reflect how our heritage is and could be. These digital twins, both the digital copies of the present and the digital proposals of the past and future, give rise to enormous databases that have traditionally been used for the development of restoration projects, such as the one studied at the Hermitage of Vaquero, but once the work was completed, it was complex and difficult to implement as a knowledge tool. * The proposed methodology allows us to increase our capacity to divulge, protect, and conserve our heritage. Digital borders are crossed, and we obtain prototypes that can be distributed in open source to promote knowledge regardless of place, physical, or economic conditions. * On the other hand, these proposals represent a revolution at the educational level; our students can have in their hands replicas of the monuments with millimetric quality. At present, education is in a permanent change. It is necessary to incorporate all these novelties to improve the skills of our teachers and our students [60]. * On the other hand, these physical prototypes are a tool that opens the doors to that aforementioned universal accessibility through typological models of our heritage. * As has been seen in the discussion of results, this way of working can be extrapolated in different subjects, such as teaching, construction, architecture, pathologies, history, etc. In short, all of this article illustrates a new system for the generation of physical prototypes that will allow us to conserve art in new ways, and allow us to improve our teaching and outreach tools. _\"Beauty perishes in life but is immortal in art\"--_
