Projects for a “disconnected” heritage. A new identity for archaeological landscapes system of Marmilla

This paper is part of a broader research framework that aims to develop strategies for knowledge and intervention on the huge prehistoric and protohistoric archaeological heritage of Sardinia, focusing on the historical region of Marmilla. The method is based on the analysis of the relationships between the site and the rural landscape and the systematization of archaeologies with existing multi-layered settlement networks. Specifically, this paper triggers a process that aims to bring attention back to the places of the archaic, proposing services and routes that can promote their visibility and, consequently, make them known and appreciated, activating a virtuous mechanism of valorization. The objectives of the work are reconstructing the identity of the places and preserving this unique heritage. Through the reinterpretation of existing features, a current and contemporary response is proposed to interpret the sites' needs in relation to accessibility in the broadest sense of the term. Some sites already appear to be partially equipped with accommodation and reception facilities, but these are often oversized or poorly functioning. Architectural and landscape design then becomes a necessary tool for fruition and enhancement, through actions that are focused on the maintenance and updating of existing buildings of proximity, the insertion of new minimal devices, paths, and coverings in archaeological areas, but also on the issue of the management of excavated material and processes related to the needs of the archaeological site. At the same time, however, the project is also a tool for general consideration, verification and fine-tuning of possible approaches and paradigms. The principles of intervention invoke the concepts of enclosure, by redefining access thresholds and limits, land and soil manipulation, and excavation, as a means through which to bring out the materiality and massiveness of the built environment and to provoke deep relationships between the present landscape and archaeology. The case studies are part of a network of archaeological sites from the Nuragic period (1700-800 B.C.) that are strongly interconnected and are located in Marmilla, a historical region of central Sardinia. We find Sa Scaba 'e Cresia in Morgongiori, Nuraghe Cuccurada in Mogoro, Sa Domu 'e S'Orcu in the jara of Siddi, Nuragic Villagio Brunk 'e s'Omu in Villaverde, Nuraghe Su Mulinu in Villanovafranca, Nuraghe Santu Miali in Pompu and the Sacred Well of Sant'Anastasia in Sardara
