Post-graduate teaching workshop as part of the course “Fondamenti metodologici dell’analisi dell’architettura”. The students work focused on the historical, constructive and stratigraphic preliminary knowledge of the church of San Michele Arcangelo, the first building designed by Giovan Battista Caniana (1671-1754). The work also involved the materials and decays survey, together with the structural failure survey, as a base for the setting of the general criteria for the project.
