LA CONSERVAZIONE DEL PATRIMONIO COSTRUITO: IL RECUPERO DEI CENTRI STORICI MINORI DEL CILENTO E VALLO DI DIANO

In the Second World War, Italy was affected by a phenomenon of industrialization that influenced the development of many urban systems distributed predominantly in the major industrial poles and along the coastal areas of the Peninsula. Territories not affected by this process, the so-called "Internal Areas", have been progressively abandoned, a phenomenon that is still in progress, with a consequent strong economic downturn and a sharp reduction in the supply of essential services. A recent analysis has shown that urban centers, predominantly smaller centers, included in these internal areas: - they involve high social costs for the state they pay for the production and consumption processes currently in place. Among the most important issues are hydrogeological disruption, loss of biological diversity, degradation of human landscapes and loss of traditional knowledge; - have little access to essential services such as health, education, mobility and virtual connectivity (Internet access), services that today in Europe identify the right of citizenship; - they have enormous potential for economic development for the huge unused land capital (agroforestry systems, building capital, traditional knowledge). In a broad sense, research seeks to identify a strategic approach aimed at the recovery and upgrading of smaller historical centers, including in the interior areas of Cilento and Vallo di Diano, in the province of Salerno. This approach moves from the need to identify the criticalities to be faced (lack of functions, equipment and services, hydrogeological vulnerability, seismic, etc.) and resources to be re-valued, namely the peculiarities of the material nature (environmental, geomorphological, typological, constructive) and intangible (local uses and traditions, enograstronomic, cultural, tourist potential, etc.). Specifically, in this contribution, the analytical approach to a case study is presented: the municipality of Ceraso, included in the "Cilento Interno" area. The approach concerned in particular the technological characterization of recurring building typologies, typical of the local construction tradition, with particular reference to the lithological characteristics and the seismic vulnerability of recurrent masonry
