The ancient estate of Conca at the edge of the pontine marshes, between the views, surveys and historical maps

In territory corresponding to the ancient estate of Conca that stretches from Le Ferriere to Tower Astura, coexist elements of strong environmental and social degradation, as a solid waste landfill and the site of a ex nuclear power plant, and natural elements such as the river Astura already Conca, an ancient fluvial corridor that connected the landscapes of the valley of Conca and the coast in a kind of organic relationship between the natural and urban environments. This area has ancient origins and collects emergencies significant archaeological, architectural and environmental, whose knowledge and appreciation could redevelop and recover highly degraded area and make the valley a product attractive to the architectural scale and of the landscape. On the basis of an ongoing study that is part of a research on basin of the river Astura, in this paper we present a reading of the territory of ancient Conca, highlighting the methodology used to perform graphic investigations, iconographic, literary and instrumental on architectural, archaeological and nature episodes more important, also aimed at the formation of a land information system.
