Dal castrum altomedievale al restauro settecentesco: storia e archeologia del castello di Sorrivoli (Roncofreddo - FC)

The methods and tools used to determine the history of construction and building techniques of the castle of Sorrivoli (Roncofreddo - FC) are here described. This is a research project carried out within a study coordinated by the teaching of Medieval Archaeology (University of Bologna), which has the purpose of conducting a census of all the medieval castles in Romagna. There is certain news from the tenth century concerning the castle to be studied. However, the investigations have shown that the standing preserved structures must be dated from the fourteenth century onwards. The system of photogrammetric survey of the walls and the technique of threedimensional modelling of the structures are here described. An extended part of this paper is also devoted to results of stratigraphic, typological, geological, metrological and comparative mensio-cronological analysis. No disponible
