Abstract
Abstract. The study presents the results of the application of a multidisciplinary methodology for a deeper understanding of historical buildings. 3D integrated surveys and stratigraphic methods can together make it possible to date the principle construction and evolution phases of historical buildings for which a thorough historical documentation does not exist for our time.The case-study presented involves the Franciscan monastery and adjacent Immacolata church in Troina, which is a small medieval town located in the north-eastern part of Sicily.The small number of historical records has only allowed for the dating of the monastery's foundation and of a few of transformation phases. Contrarily to this, various markings on the surfaces of the walls indicate rather the presence of numerous construction phases.The inaccessibility of parts of the internal spaces, as well as the existence of a sharp incline of the road and of very high walls along scant sections of the road, are the reasons for having chosen to carry out a 3D laser-scanning survey campaign. It made it possible to document the overall area and the relationship between the different parts of the complex. The integration between 3D laser scanning and photo-modelling methods made it possible to highlight the details, anomalies, traces and signs of the stratifications over time. The results of this integrated survey were explained in a series of graphic elaborations in support to the following stratigraphic investigation, to put in order the numerous traces discovered.
Highlights
The Italian territory as a whole, but in particular the Sicilian one, is extremely rich in historic town centres and architectural stratification, due to the numerous interventions and transformations carried out in the distant past
On the other hand though, the same techniques can become an effective instrument in the ‘interdisciplinary cooperation”, when they are capable of interacting and clearly presenting the necessary information to make new specialistic readings belonging to other scientific fields
No systematic and in-depth investigations had been conducted on this site, which includes both the Franciscan convent and the ancient Immaculate Conception church in Troina
Summary
The Italian territory as a whole, but in particular the Sicilian one, is extremely rich in historic town centres and architectural stratification, due to the numerous interventions and transformations carried out in the distant past The evolution of these structures are only rarely well documented in a clear and thorough manner. On the other hand though, the same techniques can become an effective instrument in the ‘interdisciplinary cooperation”, when they are capable of interacting and clearly presenting the necessary information to make new specialistic readings belonging to other scientific fields In line with this methodological presumption, a multidisciplinary study was carried out one of the lesser known architectural samples of which the Sicilian territory is plentiful.
