Perseus with the Head of Medusa

Hercules and Cacus is an Italian Renaissance sculpture in marble to the right of the entrance of the Palazzo Vecchio in the Piazza della Signoria, Florence, Italy. It has a complicated and highly political history, but the finished work is by the Florentine sculptor Baccio Bandinelli mostly from 1525 to completion in 1534. It was commissioned as a pendant to Michelangelo's David, which had been commissioned by the republican council of Florence, under Piero Soderini (gonfaloniere for life), to commemorate the victory over the Medici.

The Medici lions are a pair of marble sculptures of lions: one of which is Roman, dating to the 2nd century AD, and the other a 16th-century pendant. Both were by 1598 placed at the Villa Medici, Rome. Since 1789 they have been displayed at the Loggia dei Lanzi in Florence. The sculptures depict standing male lions with a sphere or ball under one paw, looking to the side. Copies of the Medici lions have been made and publicly installed in over 30 other locations, and smaller versions made in a variety of media; Medici lion has become the term for the type. A similar Roman lion sculpture, of the 1st century AD, is known as the Albani lion, and is now in the Louvre. Here, the stone used for the ball is different from the basalt body. Both may derive from a Hellenistic original.

The Loggia dei Lanzi, also called the Loggia della Signoria, is a building on a corner of the Piazza della Signoria in Florence, Italy, adjoining the Uffizi Gallery. It consists of wide arches open to the street. The arches rest on clustered pilasters with Corinthian capitals. The wide arches appealed so much to the Florentines that Michelangelo proposed that they should be continued all around the Piazza della Signoria.

The Pasquino Group (also known as Menelaus Carrying the Body of Patroclus or Ajax Carrying the Body of Achilles) is a group of marble sculptures that copy a Hellenistic bronze original, dating to ca. 200–150 BCE. At least fifteen Roman marble copies of this sculpture are known. Many of these marble copies have complex artistic and social histories that illustrate the degree to which improvisatory "restorations" were made to fragments of ancient Roman sculpture during the 16th and 17th centuries, in which contemporary Italian sculptors made original and often arbitrary and destructive additions in an effort to replace lost fragments of the ancient sculptures.One of the most famous versions of the composition, though so dismembered and battered that the relationship is scarcely recognizable at first glance, is the so-called Pasquin, one of the talking statues of Rome. It was set up on a pedestal in 1501 and remains unrestored. A version of the group, probably intended to represent other Homeric figures, is part of the Sperlonga sculptures found in 1957.

The Republic of Florence, officially the Florentine Republic (Italian: Repubblica Fiorentina, pronounced [reˈpubblika fjorenˈtiːna], or Repubblica di Firenze), was a medieval and early modern state that was centered on the Italian city of Florence in Tuscany. The republic originated in 1115, when the Florentine people rebelled against the Margraviate of Tuscany upon the death of Matilda of Tuscany, who controlled vast territories that included Florence. The Florentines formed a commune in her successors' place. The republic was ruled by a council known as the Signoria of Florence. The signoria was chosen by the gonfaloniere (titular ruler of the city), who was elected every two months by Florentine guild members. During the Republic's history, Florence was an important cultural, economic, political and artistic force in Europe. Its coin, the florin, became a world monetary standard. During the Republican period, Florence was also the birthplace of the Renaissance, which is considered a fervent period of European cultural, artistic, political and economic "rebirth".The republic had a checkered history of coups and countercoups against various factions. The Medici faction gained governance of the city in 1434 under Cosimo de' Medici. The Medici kept control of Florence until 1494. Giovanni de' Medici (later Pope Leo X) reconquered the republic in 1512. Florence repudiated Medici authority for a second time in 1527, during the War of the League of Cognac. The Medici reassumed their rule in 1531 after an 11-month siege of the city, aided by Emperor Charles V. Pope Clement VII, himself a Medici, appointed his relative Alessandro de' Medici as the first "Duke of the Florentine Republic", thereby transforming the Republic into a hereditary monarchy.The second Duke, Cosimo I, established a strong Florentine navy and expanded his territory, conquering Siena. In 1569, the pope declared Cosimo the first grand duke of Tuscany. The Medici ruled the Grand Duchy of Tuscany until 1737.

The Palazzo Vecchio (Italian pronunciation: [paˈlattso ˈvɛkkjo] "Old Palace") is the town hall of Florence, Italy. It overlooks the Piazza della Signoria, which holds a copy of Michelangelo's David statue, and the gallery of statues in the adjacent Loggia dei Lanzi. Originally called the Palazzo della Signoria, after the Signoria of Florence, the ruling body of the Republic of Florence, this building was also known by several other names: Palazzo del Popolo, Palazzo dei Priori, and Palazzo Ducale, in accordance with the varying use of the palace during its long history. The building acquired its current name when the Medici duke's residence was moved across the Arno River to the Palazzo Pitti.

The Fountain of Neptune in Florence, Italy, (Italian: Fontana del Nettuno) is situated in the Piazza della Signoria (Signoria square), in front of the Palazzo Vecchio. The fountain was commissioned by Cosimo I de' Medici in 1559 to celebrate the marriage of Francesco de' Medici I to Grand Duchess Joanna of Austria. Cosimo I de' Medici was the Duke of Florence from 1537-1569 and responsible for a vast number of architectural and artistic elements in Florence that still exist today. The fountain was designed by Baccio Bandinelli, but created by Bartolomeo Ammannati with the assistance of several other artists between 1560 and 1574. It incorporates a series of mythological figures and iconographies that symbolize both Cosimo I de' Medici's power and the union of Francesco and Joanna. It has sustained a great deal of damage over the years due to vandalism and general mistreatment but underwent a major restoration completed in 2019 that restored it to its original glory.

Piazza della Signoria (Italian pronunciation: [ˈpjattsa della siɲɲoˈriːa]) is a w-shaped square in front of the Palazzo Vecchio in Florence, Italy. It was named after the Palazzo della Signoria, also called Palazzo Vecchio. It is the main point of the origin and history of the Florentine Republic and still maintains its reputation as the political focus of the city. It is the meeting place of Florentines as well as the numerous tourists, located near Palazzo Vecchio and Piazza del Duomo and gateway to Uffizi Gallery.

The Crossing of the Red Sea, also known as The Crossing of the Red Sea and Moses Appointing Joshua, is a fresco painting by the Italian artist Agnolo di Cosimo, known as Bronzino, finished in 1542. It depicts the Nation of Israel crossing the Red Sea from the book of Exodus and Moses commissioning Joshua to lead the Israelites into the promised land from the book of Numbers. It is housed in the Palazzo Vecchio, Florence. In 1540, Cosimo I de' Medici and/or his wife, Eleanor of Toledo, commissioned this and other frescoes for Eleanor's private chapel. Three of the four walls of the small chapel found on the second floor of the palace are covered with works telling the story of Moses.

The Equestrian Monument of Cosimo I is a bronze equestrian statue executed by Giambologna from 1587 to 1594, and erected in 1594 in the Piazza della Signoria in Florence, region of Tuscany, Italy.

The Studiolo is a small painting-encrusted barrel-vaulted room in the Palazzo Vecchio, Florence, Italy. It was commissioned by Francesco I de' Medici, Grand Duke of Tuscany. It was completed for the duke from 1570 to 1572, by teams of artists under the supervision of Giorgio Vasari and the scholars Giovanni Batista Adriani and Vincenzo Borghini. This small room was part-office, part-laboratory, part-hiding place, and part-cabinet of curiosities. Here the prince tinkered with alchemy and kept his collection of small, precious, unusual or rare objects. The walls and ceiling were decorated with paintings showing a similar variety of subjects, some showing exotic forms of industry and others mythology. The inset paintings are now all that remains in the room of the original contents. They are rather larger than what is normally meant by the term cabinet painting. The late-Mannerist decorative program of paintings and sculpture was based on items encompassed by the collection. The object collection itself was stored in ~ 20 cabinets. In the center is a fresco of Prometheus receiving jewels from nature, commenting on the interplay of divine, nature, and humanity, that is the goal of both artistic and scientific interests.

The Palazzo delle Assicurazioni Generali is a building in the Piazza della Signoria in Florence, Italy. Originally the Palazzo Fenzi, built for the Fenzi banking family and designed in the Neo-Renaissance style by Giuseppe Martelli and is one of the very few purpose built commercial buildings in the centre of the city though it housed on the upper floors reception rooms for the Fenzi family. The site was formerly occupied by the "Pisan Loggia" and the "Chiese de Santa Cecilia" While the architecture of the palazzo is undoubtedly inspired by that of the Palazzo Medici Riccardi, also in Florence, the Palazzo delle Assicurazioni Generali was never intended to be a private house but the local headquarters of the General Insurance Company which was founded in Trieste in 1831. There are other Palazzi delle Assicurazioni Generali in other Italian cities most notably Rome and Milan. During the latter half of the 19th century the Assicurazioni Generali (commonly known as "Generali") were expanding not only in Italy but also throughout Europe. The Assicurazioni Generali generally employed retrospective architectural style to reflect the surroundings of their offices in Rome the palazzo imitates the Palazzo Venezia which it faces, while in Milan the Palazzo delle Assicurazioni Generali is in a form of 19th century Baroque known as Beaux Arts. The Florence Palazzo delle Assicurazioni unsuccessfully vies for dominance in the piazza with the more historical and architecturally important Palazzo Signoria, today known as the Palazzo Vecchio. In spite of its height and size the architecture of the Palazzo delle Assicurazioni Generali harmonises with that of the surrounding buildings, and does not appear as a new imposter in the piazza. However, this is not a view shared by all, one source describes those buildings of Piazza della Signoria occupied by banks and Insurance companies as "seeming to belong to some cold northern climate rather than to the city that gave birth to the colour and vitality of the Renaissance" Part of the ground floor is home to one of Florence's more fashionable and historical cafés – "Rivoire", founded in 1872.
