Materiali e superfici di una città stratificata. Gli studi su Saluzzo tra fonti documentarie e analisi sul costruito

The study undertaken for the Piano di manutenzione delle superfici di facciata del centro storico di Saluzzo has provided for an articulated and complex research phase which, through the critical survey of the building facades, the analysis of the materials and archival research, has made it possible to return the data acquired with graphic tables, tables and colour notation charts. In order to compose an exhaustive information framework of possible indications on materials and techniques for facade, stratigraphic analyses have been carried out, which also proved to be useful to integrate the data that emerged from bibliographic and historiographic sources. The historical archive of the city of Saluzzo has been an essential source of research, with the examination and study of documentary sources from the Modern Age documenting construction sites in the city. The research has made it possible to reconstruct the main renovations of the borgo di mezzo, in the lower part of the historical city, between the end of the XVIII century and the beginning of the XX century, providing original data on the maintenance of the historic building, the rebuilding of the fronts or the restoration of the facades.
