The Palatine Gallery and Royal Apartments are situated in the Pitti Palace, the former residence of the Grand Dukes of Tuscany (Medici and Lorraine) and of Italian regal family. In the sublime Royal Apartments, which can be accessed from the majestic staircase worked by Bartolomeo Ammannati, are kept furnishings and accessories from the sixteenth to the nineteenth century. Specifically, you can appreciate the furniture brightened with the famous procedure of commesso fiorentino (Florentine mosaic). This technique for working of semi-precious stones is still polished today by the Opificio delle Pietre Dure in Florence, a workshop famous all through the world.
