Sustainable conservation: the state of art and the need of guidelines about protection and enjoyment of the archeological Heritage

Within the scientific debate about the conservation, in general, of Cultural Heritage and, in particular, of Archaeological Heritage which are characterized by a dual tangible and intangible nature; and in consistence with Technological Culture for its features concerning the right development and enjoyment of the Heritage, the present essay offers a critical interpretation of the literature about a protection system with an architectural shelter for archaeological sites. On the basis of the critical elements detected in the activities that took place over the past sixty years, this essay underlines the absolute impossibility to postpone the definition of the guidelines which need to be always based on a case-by-case principle in order to bring workers towards an aware conservation, enhancement and enjoyment of the Archaeological Heritage. It is impossible to postpone the creation of operational models which allow us to set up a contemporary high-performance, reliable, sustainable but also reversible protection system (with morphological, typological, technical and constructive solutions suitable for the potential significance of the Heritage itself) in order to cope with significant and variable meanings that would or could be given by the future generations.
