Tipologie insediative urbane in età medievale. Un caso di studio: Castelsardo

The doctoral thesis analyzes the urban development throughout the Middle Ages of the fortified village of Castelgenovese, later renamed Castellaragonese and finally Castelsardo. The peculiar nature of the terrain have kept relatively intact the original urban core, enabling comprehensive investigation of the stages and rules followed in medieval times. The methodological process that led the research is based on topographic surveys carried out on site, bibliographic research and the deepening of the main texts relating to the military in Sardinia, together with an analysis of the historical center of Castelsardo projects. Through an interdisciplinary study of archaeological and city planning sources, the research project analyzed and elaborated the development of the medieval village, limited in its expansion but preserved from the destructive actions which instead have affected other centers of the territory. The historical and archaeological aspect was found next to the architectural and urban planning to provide a more complete elaboration of the meaning of the medieval city as urban form. From a technical-practical point of view it is paid to the analysis of individual elements of investigation provided by the analysis of the historical nucleus of the settlement plans, detailed plans and surveys in the field, needed to reach a full understanding of the construction mode of the time
