In 1563, with the transfer of the ducat's capital from Chambéry to Turin, Emanuele Filiberto of Savoy established his residence in the palace of the bishop at the Duomo; already in 1584, Carlo Emanuele I entrusted the architect Ascanio Vittozzi with the construction of a new factory. After 1643, with the regency of Maria Cristina of France, the direction of the work passed to Carlo di Castellamonte and then to Carlo Morello. http://www.museireali.beniculturali.it/index.php/it/il-complesso/palazzo-reale
