Il restauro delle superfici di Palazzo Madama a Torino: metodo ed esiti

The examination of the different interventions carried out on a single building over more than a century offers the opportunity to notice the change of philosophy and operating procedures of restoration over time. The analysis of the documentation concerning the restoration interventions carried out on the Juvarrian façade of Palazzo Madama in Turin, starting from the mid- XIXth century until today, allows to identify both the principles that guided the restorers in the choice of the modalities of intervention and the change in materials and operating techniques adopted. The latter are the result of the evaluation of both the outcomes and the critical issues that emerged from previous interventions, and of what the market was and still is able to offer. This work is carried out through the analysis of the operational results taking into account also the disciplinary recommendations elaborated in the time frame considered
