In October of 2013 restoration on the Sala delle Asse began. The project to restore the decoration, being carried out by the Opificio delle Pietre Dure in Florence, under the Direzione Regionale per i Beni Culturali e Paesaggistici and advised by a scientific committee, has three objectives: blocking the deterioration of the paintings caused by environmental conditions and chemical processes, cleaning the surface and recovering, where possible, visibility of the original decoration. The works carried out so far have led to extraordinary discoveries.
