The cultural landscape, material and intangible heritage and sustainable tourism, appropriately integrated with the specific economic-productive and social-anthropological value of the places, emerge as useful resources to strengthen territories, especially the inland ones, more fragile and marginal. In Italy, the “inland areas” occupy more than 60% of the area with 23% of the population. It is a widespread reality where tourism still plays a modest role compared to the main poles of attraction, below the potential linked to the wealth of preserved identity assets and the unexpressed tourist offer. This underutilized heritage is part of the latent capital that the “National Strategy for Inland Areas” and the “Strategic Tourism Plan” aim to reactivate. For the emerging “touriscape” in marginal areas the presence of “attractors” and “gateways”, within a matrix of diffused “poles”, appears a necessary condition. However, it is not sufficient to ensure the success of the strategy. It is necessary that this is translated into projects attentive to the contexts and specificity of the places, measuring with the deep exploration of the opportunities offered by marginality. The proposed methodological approach assumes marginality as a concept and tool of the architecture project. Central is the relational theme, to enhance heritage and places as architectures of simultaneous relationships. This topic is applied a case study and project in the territory of Barbagia Nuorese in Sardinia. On an island, the inland is a marginal area par excellence, where we are confined to a microcosm and the adoption of innovative attitudes and strategies to compete and survive becomes a form of resistance, as the landscape produced by an ongoing project that constantly transforms the surplus in exchange for something advanced, permanent and identity. The inland, as the margin, is revised as a space of possibility and paradigm of the project.
