The Galleria Palatina, together with the Royal and Imperial Apartments, occupies the entire first floor of Palazzo Pitti. The lavish Gallery was founded between the end of the eighteenth century and the first decades of the nineteenth century by the Habsburg-Lorraine family, who hung about 500 masterpieces in the ceremonial rooms chosen from the main Medici’s collections. It is an impressive selection, which includes the largest concentration of paintings by Raphael in the world, as well as invaluable works by Titian, Tintoretto, Caravaggio and Rubens. The paintings in their lavish frames entirely cover the walls of the rooms which are enriched by sculptures, vases and tables with semi-precious stone inlays, typical of 17th-century galleries. The sensational series of frescoes by Pietro da Cortona for Grand Duke of Tuscany Ferdinando II de’ Medici, realized between 1640 and 1647 in the Planet Rooms, adds to the unique charm of the Gallery, where every work of art is enhanced by the setting and the furnishings. The Royal Apartments occupy the fourteen magnificent rooms of the right wing of the building and they contain a rich collection of furniture, objects and works of art dating from the sixteenth to the nineteenth century.
