Vol. 15, no. 4

The documentation of the urban historical heritage is the preliminary step to identify the correct strategies for its protection and enhancement. To achieve this aim it is necessary to acquire a graphic documentation at the different scales of detail required by a multi-layered system as the historical landscape; this complexity can now be explored integrating traditional and digital survey methods and representation methodologies. Traditional methods, in particular, are characterized by a direct contact with places; this condition guarantee a deepest perception and a total immersion in the landscape integrating and giving quality to the considerable amount of data offered by recent technologies; this approach has been applied in the survey of the historical city of Cagliari in which the medieval districts of Marina, Stampace, Villanova and Castello retain a great part of the modern walled system built since the fourteenth century until the first half of the nineteenth century and a lot of interesting buildings designed for civil, public and religious use.

The contribution proposed is a part of a research aimed at the definition of methodologies for the analysis and representation of the landscape of Sardinia, with particular reference to one of its most important and characteristic versions: the landscape of the wetlands. The history of the city of Cagliari is strongly linked to the sea and the lagoons, elements that constituted the authentic “settlement principle” where the lagoons, in particular, were sources of decisive resources as well as for fishing, for the landing (especially the western ponds) and salt extraction (mainly from the Molentargius pond). The case study consists in a part of the regional natural park Molentargius-Saline, a system of considerable environmental and landscape value that hosts examples of industrial archeology. Through a multi-scale approach that links traditional and IT tools it is possible to define some representative graphic models of the studied landscape in order to plan its protection and enhancement. The comparison between historical maps and aerial images here presented is the first step of a path of knowledge that explores, analyzes and wants to highlight the most important transformation that occurred in this area since the nineteenth century and a partial preservation of historical cultural landscape.
