The Palazzo Pitti, in English sometimes called the Pitti Palace, is a vast mainly Renaissance palace in Florence, Italy. The palace was bought by the Medici family in 1549 and became the chief residence of the ruling families of the Grand Duchy of Tuscany. The Palatine Gallery on the first floor contains a large ensemble of over 500 principally Renaissance paintings, which were once part of the Medicis' and their successors' private art collection. The gallery, which overflows into the royal apartments, contains works by Raphael, Titian, Correggio, Rubens, and Pietro da Cortona.
