The Tesoro dei Granduchi, known as “Museum of the Argenti” (silverware), is located on the ground and mezzanine floor of the Pitti Palace, and occupies the premises that were once the summer Apartment of the Medici family, decorated in 1635 by Grand Duke Ferdinando II in preparation for his wedding with Vittoria della Rovere. The Museum houses the treasure of the Medici: the vases in semi-precious stone of Lorenzo the Magnificent, the cameos and carvings of Cosimo I; the quartz crystals of Francis I, the ambers of Mary Magdalene of Austria, the ivory vases of Mattias de’ Medici, the famous collection of jewels belonging to Anna Maria Luisa. The silverware comes from the so-called “Treasure of Salzburg” that is from the collections of the bishops of Salzburg, brought to Florence by Ferdinand III of Lorena in 1815. The Museum also hosts an important collection of jewels realised between the 17th and the 20th century and an important section dedicated to contemporary jewellery.
