The case history of Low Romagna Fiorella Dallari, Centre for Advanced Studies in Tourism, Alma Mater Studiorum - University of Bologna, fiorella.dallari@unibo.it The objective of this relation is to present a case study focused on the design of a tourist route, thematic and in interstices territories, connected to the memory of the tangible and intangible heritage of the First World War (2014-2018) that is being to commemorate the centenary. This widespread heritage many times is invisible because forgotten (Forristal, 2013; Carson, 2013; Kerr, 2013), erased, mutilated, and often misrepresented. The project is designed in the context of numerous studies and research dedicated to cultural itineraries along with an academic training. The goal is to work out a model of local development in an international perspective within a small community, peripheral to the touristic track. The new tourist territories, practices, products and temporalities are building up from interstitial spaces and new practices. The construction of urban networks (Beltramo, 2013) and local small tourism attractions are very strategic to support minors new places, a tourism borderscapes. The relation takes into account the framework for application of the literature devoted to various central themes in the postmodern practice guide, or rather linked to the new life tourism (Gola et alii, 2012), as Heritage, particularly memorable experiences (Fitzsimmons et alii, 2000) , authenticity (Cohen et al, 2012), innovation (Williams et al, 2011) and creativity (Richard, 2011). The case study consists of an area of Lower Romagna (Italy), peripheral to the Adriatic coast, seaside tourist destinations for over 150 years with 30 million of touristic overnight stays. This territory of Lower Romagna (104.000 people, about 480 kmq and 90.000 overnight stays) is characterized by a network of small centres, an historical and agricultural landscape with a longestablished social and economic cooperation and an notable local development. From the January 1st, 2000 the nine Municipalities have given birth to the Association of the Low Romagna (Bassa Romagna), a political territorial system with its own identity and a role now recognized in the regional and national context. The methodology used is descriptive (heritage, landascape, community), with collection and analysis of information material, statistical data with the use of tools for social and geographical research (questionnaires and workshops with opinion leaders and public and private actors).
