During this time, the city generated great wealth due to the mining industry that developed in the Colline Metallifere hills. One can see the cultural and artistic influence of artists from Pisa and Siena, such as Giovanni Pisano, Ambrogio Lorenzetti and Gano di Fazio. The objects that make up the museum’s collection come from various religious buildings located throughout in the city. Some artworks have been provided by local parishes while others, like the ‘Maestà’ by Ambrogio Lorenzetti, belong to the city.
This painting, created as an altarpiece for the church of San Pietro all’Orto was rediscovered in the monastery’s cellars during the late nineteenth century and identified as a work by Lorenzetti thanks to writings by Vasari. A room in the museum hosts the reconstruction of a loggia from the Duomo’s facade with original sculptures by Giovanni Pisano, removed during their restoration in 2000. In another room, one can find interesting medieval relief works, placed on the Duomo’s counter facade in the mid-nineteenth century. These probably came from a more ancient sacred building.
