Invisible archeology is made of investigated and completely re-buried sites, often in the midst of large containers or infrastructures of the contemporary territory.The invisible archeology landscapes come from extensive excavations - especially after major territorial changes - and from the lack of protection models commensurate with the relevance of the finds. It is not easy to communicate the possible cultural sense of discoveries that do not always are monumental but often difficult to understand compared to their ancient function.
The case of the Portuense district, starting from the New Fair of Rome, was a formidable occasion to reflect on the possible role of archeology in territories of urban sprawl, compared to the reorganization of their operation, renewing the relationship between research, protection and valorization. Thanks to the patient search for new ways of dialogue between archeology, architecture and landscape, the valorization project tends to historical narrative, moving from developmental sequences as particularly significant, ie capable of making understandable the perception of a territory - even vast - and archaeologically different sites - dug o reburied - overcoming the dictatorship of objects and properties in favor of dynamic and ever changing assets.
The Guidelines are born from the need to give coherent and "unique" answers to the questions of use and arrangement of the areas where the archaeological are. These are the questions posed by heterogeneous subjects - mostly private developers or service providers - involved in the urban fabric and infrastructural transformation. The goal is to indicate a possible integration between simultaneous uses of the open "archaeological" space and exigences of tutelage and valorization of the finds, with the result of establishing new collective meanings and new landscapes.
The reflections contained in this research experience, marked by fundamental application and design parts, is the result of a comparison of disciplinary perspectives, different institutional roles and expertise of a university department (DiAP Department of Architecture and Project - Sapienza University of Rome) and an Archaeological Superintendency (Superintendence for Archaeological Heritage).
