The Palazzo Pitti (sometimes called the Pitti Palace) is a vast mainly Renaissance palace in Florence, Italy. It is situated on the south side of the River Arno, a short distance from the Ponte Vecchio. The core of the present palazzo dates from 1458 and was originally the town residence of Luca Pitti, an ambitious Florentine banker. It was bought by the Medici family in 1539 as the official residence of the ruling families of the Grand Duchy of Tuscany.
Early in the 19th century, the palazzo, by then a great treasure house, was used as a power base by Napoleon, and much later served for a brief period as the principal royal palace of the newly united Italy. In the early 20th century, the palazzo together with its contents was given to the Italian people by King Victor Emmanuel III; subsequently its doors were opened to the public as one of Florence's largest art galleries. Today, housing several minor additions in addition to those of the Medici family, it is fully open to the public.
