Because of the long entrance lines we decided to forgo the interior tour of the Pitti Palace which we toured in 1982. I did, however, get several images of the exterior.

The Palazzo Pitti (Italian pronunciation: [paˈlattso ˈpitti]), in English 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.

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. It grew as a great treasure house as later generations amassed paintings, plates, jewelry and luxurious possessions.

In the late 18th century, the palazzo was used as a power base by Napoleon and later served for a brief period as the principal royal palace of the newly united Italy. The palace and its contents were donated to the Italian people by King Victor Emmanuel III in 1919.

The palazzo is now the largest museum complex in Florence. The principal palazzo block, often in a building of this design known as the corps de logis, is 32,000 square metres. It is divided into several principal galleries or museums detailed below.

History
Early history
The construction of this severe and forbidding building was commissioned in 1458 by the Florentine banker Luca Pitti (1398–1472), a principal supporter and friend of Cosimo de' Medici. The early history of the Palazzo Pitti is a mixture of fact and myth. Pitti is alleged to have instructed that the windows be larger than the entrance of the Palazzo Medici. The 16th-century art historian Giorgio Vasari proposed that Brunelleschi was the palazzo's architect, and that his pupil Luca Fancelli was merely his assistant in the task, but today it is Fancelli who is generally credited. Besides obvious differences from the elder architect's style, Brunelleschi died 12 years before construction of the palazzo began. The design and fenestration suggest that the unknown architect was more experienced in utilitarian domestic architecture than in the humanist rules defined by Alberti in his book De Re Aedificatoria.

Though impressive, the original palazzo would have been no rival to the Florentine Medici residences in terms of either size or content. Whoever the architect of the Palazzo Pitti was, he was moving against the contemporary flow of fashion. The rusticated stonework gives the palazzo a severe and powerful atmosphere, reinforced by the three-times-repeated series of seven arch-headed apertures, reminiscent of a Roman aqueduct. The Roman-style architecture appealed to the Florentine love of the new style all'antica. This original design has withstood the test of time: the repetitive formula of the façade was continued during the subsequent additions to the palazzo, and its influence can be seen in numerous 16th-century imitations and 19th-century revivals. Work stopped after Pitti suffered financial losses following the death of Cosimo de' Medici in 1464. Luca Pitti died in 1472 with the building unfinished.

The Medici
The building was sold in 1549 to Eleonora di Toledo. Raised at the luxurious court of Naples, Eleonora was the wife of Cosimo I de' Medici of Tuscany, later the Grand Duke. On moving into the palace, Cosimo had Vasari enlarge the structure to fit his tastes; the palace was more than doubled by the addition of a new block along the rear. Vasari also built the Vasari Corridor, an above-ground walkway from Cosimo's old palace and the seat of government, the Palazzo Vecchio, through the Uffizi, above the Ponte Vecchio to the Palazzo Pitti. This enabled the Grand Duke and his family to move easily and safely from their official residence to the Palazzo Pitti. Initially the Palazzo Pitti was used mostly for lodging official guests and for occasional functions of the court, while the Medicis' principal residence remained the Palazzo Vecchio. It was not until the reign of Eleonora's son Francesco I and his wife Johanna of Austria that the palazzo was occupied on a permanent basis and became home to the Medicis' art collection.

Land on the Boboli hill at the rear of the palazzo was acquired in order to create a large formal park and gardens, today known as the Boboli Gardens. The landscape architect employed for this was the Medici court artist Niccolò Tribolo, who died the following year; he was quickly succeeded by Bartolommeo Ammanati. The original design of the gardens centred on an amphitheatre, behind the corps de logis of the palazzo. The first play recorded as performed there was Andria by Terence in 1476. It was followed by many classically inspired plays of Florentine playwrights such as Giovan Battista Cini. Performed for the amusement of the cultivated Medici court, they featured elaborate sets designed by the court architect Baldassarre Lanci.

The cortile and extensions
With the garden project well in hand, Ammanati turned his attentions to creating a large courtyard immediately behind the principal façade, to link the palazzo to its new garden. This courtyard has heavy-banded channelled rustication that has been widely copied, notably for the Parisian palais of Marie de' Medici, the Luxembourg. In the principal façade Ammanati also created the finestre inginocchiate ("kneeling" windows, in reference to their imagined resemblance to a prie-dieu, a device of Michelangelo's), replacing the entrance bays at each end. During the years 1558–70, Ammanati created a monumental staircase to lead with more pomp to the piano nobile, and he extended the wings on the garden front that embraced a courtyard excavated into the steeply sloping hillside at the same level as the piazza in front, from which it was visible through the central arch of the basement. On the garden side of the courtyard Amannati constructed a grotto, called the "grotto of Moses" on account of the porphyry statue that inhabits it. On the terrace above it, level with the piano nobile windows, Ammanati constructed a fountain centered on the axis; it was later replaced by the Fontana del Carciofo ("Fountain of the Artichoke"), designed by Giambologna's former assistant, Francesco Susini, and completed in 1641.

In 1616, a competition was held to design extensions to the principal urban façade by three bays at either end. Giulio Parigi won the commission; work on the north side began in 1618, and on the south side in 1631 by Alfonso Parigi. During the 18th century, two perpendicular wings were constructed by the architect Giuseppe Ruggeri to enhance and stress the widening of via Romana, which creates a piazza centered on the façade, the prototype of the cour d'honneur that was copied in France. Sporadic lesser additions and alterations were made for many years thereafter under other rulers and architects.

To one side of the Gardens is the bizarre grotto designed by Bernardo Buontalenti. The lower façade was begun by Vasari but the architecture of the upper storey is subverted by "dripping" pumice stalactites with the Medici coat of arms at the centre. The interior is similarly poised between architecture and nature; the first chamber has copies of Michelangelo's four unfinished slaves emerging from the corners which seem to carry the vault with an open oculus at its centre and painted as a rustic bower with animals, figures and vegetation. Figures, animals and trees made of stucco and rough pumice adorn the lower walls. A short passage leads to a small second chamber and to a third which has a central fountain with Giambologna's Venus in the centre of the basin, peering fearfully over her shoulder at the four satyrs spitting jets of water at her from the edge.

Houses of Lorraine and Savoy
The palazzo remained the principal Medici residence until the last male Medici died in 1737. It was then occupied briefly by his sister, the elderly Electress Palatine; on her death, the Medici dynasty became extinct and the palazzo passed to the new Grand Dukes of Tuscany, the Austrian House of Habsburg-Lorraine, in the person of Francis I, Holy Roman Emperor. The Austrian tenancy was briefly interrupted by Napoleon, who used the palazzo during his period of control over Italy.

When Tuscany passed from the House of Habsburg-Lorraine to the House of Savoy in 1860, the Palazzo Pitti was included. After the Risorgimento, when Florence was briefly the capital of the Kingdom of Italy, Victor Emmanuel II resided in the palazzo until 1871. His grandson, Victor Emmanuel III, presented the palazzo to the nation in 1919. The palazzo and other buildings in the Boboli Gardens were then divided into five separate art galleries and a museum, housing not only many of its original contents, but priceless artefacts from many other collections acquired by the state. The 140 rooms open to the public are part of an interior, which is in large part a later product than the original portion of the structure, mostly created in two phases, one in the 17th century and the other in the early 18th century. Some earlier interiors remain, and there are still later additions such as the Throne Room. In 2005 the surprise discovery of forgotten 18th-century bathrooms in the palazzo revealed remarkable examples of contemporary plumbing very similar in style to the bathrooms of the 21st century.

Royal Apartments
This is a suite of 14 rooms, formerly used by the Medici family, and lived in by their successors. These rooms have been largely altered since the era of the Medici, most recently in the 19th century. They contain a collection of Medici portraits, many of them by the artist Giusto Sustermans. In contrast to the great salons containing the Palatine collection, some of these rooms are much smaller and more intimate, and, while still grand and gilded, are more suited to day-to-day living requirements. Period furnishings include four-poster beds and other necessary furnishings not found elsewhere in the palazzo. The Kings of Italy last used the Palazzo Pitti in the 1920s. By that time it had already been converted to a museum, but a suite of rooms in the Meridian wing (now the Gallery of Modern Art) was reserved for them when visiting Florence officially.

The Palazzo today
Today, transformed from royal palace to museum, the Palazzo is in the hands of the Italian state. Once under the "Polo Museale Fiorentino", an institution which administers twenty museums, from 2015 it is a department of the Uffizi, as a separate and independent structure within the Ministry of Cultural Properties and Activities, and has ultimate responsibility for 250,000 catalogued works of art. In spite of its metamorphosis from royal residence to a state-owned public building, the palazzo, sitting on its elevated site overlooking Florence, still retains the air and atmosphere of a private collection in a grand house. This is to a great extent due to the "Amici di Palazzo Pitti" (Friends of the Palazzo Pitti), an organisation of volunteers and patrons founded in 1996, which raises funds and makes suggestions for the ongoing maintenance of the palazzo and the collections, and for the continuing improvement of their visual display.
