On the third floor you'll find the Gabinete del Coleccionista/"Office of the Collector", where you can see a variety of ceramics, glass, silver, enamel, and bronze. You can do something pretty unusual for a museum in this room: you can open the cabinets and drawers as you wish, as if you were at home, and discover all sorts of collector's items like keys, textiles, weapons, medals, and coins.
