“Matera città Narrata” is a project coordinated by CNR ITABC and financed by APT Basilicata aimed at the creation of a digital platform able to support the public, before and during the visit of Matera (World Heritage since 1993), providing cultural contents by multiple communicative formats. The main components are: 1) the multimedia web site, adapted also for smartphone, 2) cultural contents and applications for mobile devices (smartphone, iPad, old style mobile phone) with different operative systems. The user can choose the communicative format he prefers supported by the technology he owns. The project introduces a new approach in the re-qualification and valorisation of the cultural landscape of Matera (archaeological, historical, artistic, natural contexts, intangible heritage), focusing not only on the most important sites but on the diffused cultural heritage and in the preservation of historical memory. For the first time the urban and natural landscape of Matera has been reconstructed in 3D in nine different historical periods, from 2 million years ago until today. Moreover many inhabitants, old people and children, together with famous artists gave their contribution to the project, through their personal memories and visions and bringing here their art. So this project consists in an integrated, multidisciplinary and multidimensional network of “virtual heritage”, connecting places, ages, authors, contents, users, real world and virtual dimensions.
