The built heritage belongs to society as a whole and to both the present and future generations. For that reason all the knowledge, acquired experience and methods are not the exclusive property of the group of professionals who work to restore and rehabilitate the cathedral but belong to society in general.
There are several paradigms that guide our day-to-day tasks and the way we approach the comprehensive restoration. Accessibility, transversality, networking, the socialisation of knowledge and respect for the artefact are fundamental.
