The Magazzini del Sale (Salt Warehouses) are located inside the monumental Palazzo Comunale (Town Hall) of Siena, originally built in the thirteenth century. The main goal of the project was to connect the two main levels of the Palazzo Comunale, creating a new access to the new exhibition spaces of the Museo Civico directly from the Piazza del Campo, and to give continuity, through a new staircase, to all the floors of the building, giving a new visibility to the enclosed space between the main building and the courtyard. This intervention has changed the overall use and functionality of the building, separating different activities and creating a system of new connections. Thus, the complex of new spaces recovered have been destined for temporary exhibitions.
