Федериго да Монтефельтро
Owner of a huge amount of artistic works and the wealth accumulated over the years by the Ducal family, she appointed her granddaughter Vittoria della Rovere as her sole heiress. Following this, most of the artistic heritage of the Della Rovere family was then removed from Urbino (for example, the double portrait of the Dukes of Urbino, Federico da Montefeltro and Battista Sforza, of Piero della Francesca) and transferred to Florence to the collections of the Medici or to Rome in the Papal Palaces.
