The restoration intervention was divided into different phases aimed at returning the work to its original state. Below are the activities that were carried out:

• preliminary verification of the stability of all the constituent parts. In this phase, each element was examined in order to evaluate its structural integrity and determine its possible removal;
• removal of weeds and disinfection of biological patinas. Weeds that could have a negative impact on the structure were eliminated. Furthermore, disinfection operations were carried out to remove biological organisms that could damage the work;
• cleaning of stone surfaces and antioxidant treatment of metal elements. Stone surfaces were cleaned to remove dirt, smog deposits and other impurities. Metal elements, such as nails, brackets or other connections, were subjected to an antioxidant treatment to prevent corrosion and prolong their life;
• consolidation of the surfaces, with particular attention paid to the connections between the blocks. During this phase, interventions were carried out to improve the cohesion and stability of the stone surfaces. In particular, attention was paid to the connections between blocks to ensure they are solid and resistant.
