This room, adjacent to the eighteenth-century Venetian Hall, was reserved for the family's ancient archival collections. The room was decorated in the mid-nineteenth century with stucco and leaf gilding and is characterized by the presence of a refined embellished ceiling. In correspondence with the centre of each wall there are the coats of arms of the Miniscalchi and other noble families who carried with them, namely the Erizzo, the Moscardo and the Guerrieri. In the corners of the ceiling are allegorically represented the instruments of four noble arts - Astronomy, Painting, Architecture and Literature – together with the portraits of presumably illustrious characters in these arts but whose certain identification is difficult due to the absence of inscriptions.
