The Museum, situated on the ground floor and mezzanine of Palazzo Pitti, in what was once the summer quarters of the Grand Dukes, displays treasures collected by the Medici and Hapsburg-Lorraine dynasties. Included in the collection are splendid ancient vases that belonged to Lorenzo the Magnificent, art objects from the Cabinet of Gemstones in the Uffizi, the jewels of the Palatine Electress, and the treasures of the Princes of Salzburg, brought to Florence by Ferdinand III of Lorraine in 1814, as well as gemstones, ivory carvings, amber, paintings on glass, lace, cameos, fabrics and tapestries. Completing the collection are objects in semiprecious stone coming from the Medici collections. From the historic-scientific viewpoint, the Museo degli Argenti is noteworthy for the presence of many frescoed scenes representing allegories of science.
