Giuliano da Sangallo

Giuliano da Sangallo (born Giuliano Giamberti around 1445, died 1516) was a Florentine sculptor, architect, and military engineer of the Italian Renaissance. He is best remembered as the favorite architect of his patron, Lorenzo de' Medici. For Lorenzo, he created a villa, an Augustinian monastery, and a church built on the site of a reported miracle. Later, he also took on commissions from Pope Julius II and Pope Leo X. His work was shaped by the influence of Leon Battista Alberti and Filippo Brunelleschi, and he in turn left his mark on figures like Raphael, Leonardo da Vinci, his brother Antonio da Sangallo the Elder, and his sons Antonio da Sangallo the Younger and Francesco da Sangallo.

**Early life**

Born in Florence around 1445, Giuliano was the son of Francesco Giamberti, a woodworker and architect who worked closely with Cosimo de' Medici. This connection helped Giuliano and his brother Antonio build a close working relationship and friendship with Cosimo’s grandson, Lorenzo de' Medici. As a boy, Giuliano apprenticed with a joiner, where his skills in woodworking, building, and sculpture caught Lorenzo’s eye. Beyond his apprenticeship, he studied the works of ancient architects and more recent masters like Alberti and Brunelleschi, sharpening his eye for classical design and cementing a lifelong business partnership with Lorenzo. His first major independent commission came from the Medici family and showcased both his architectural talent and his knowledge of fortifications. Lorenzo called on him to build military defenses and manage artillery in the town of Castellina during an invasion by the Duke of Calabria. Giuliano succeeded in driving out the Calabrian forces, proving his natural ability in military construction and strategy.

**Major works**

**Medici Villa at Poggio a Caiano**

After the victory in Calabria, Lorenzo de' Medici trusted Giuliano enough to commission him to design a villa in Poggio a Caiano, chosen through a competition. Construction began in 1485 but remained largely unfinished during Lorenzo’s lifetime; it was completed later by Lorenzo’s son, Giovanni, after he became Pope Leo X. Giuliano’s design incorporated classical elements like Ionic columns and a façade modeled on an ancient temple. The Medici Villa at Poggio a Caiano stands as one of the earliest examples of a Renaissance-style country villa and inspired many later architects.

**Santa Maria delle Carceri**

In 1484, a child in Prato claimed to have seen a painting of the Virgin Mary and the infant Jesus come to life on the wall of the local jail. The townspeople declared it a miracle and decided to build a church on the spot. Lorenzo de' Medici again hired Giuliano for the project. His design drew heavily from Alberti and Brunelleschi, featuring a Greek cross plan—four arms of equal length extending from a central nave—a layout rarely used in the Renaissance up to that point. Construction began in 1486, but the church’s façade remains unfinished today.

**Reggia in Naples**

In 1488, after initial plans for the Poggio a Caiano villa were set, Lorenzo sent Giuliano to build a castle for Ferrante of Aragon, the King of Naples. This was part of a broader political strategy: when Italian city-states weren’t at war, they exchanged gifts and sent artists and architects as diplomatic gestures. By sending Giuliano, the Medici also aimed to spread Florentine culture across Italy. Giuliano planned to build the castle on open land near Castel Nuovo, but it was never constructed; only his sketches survive. The palace design shared features with the Medici Villa, including a raised platform, two stairways leading to the main entrance, a portico between them, and a rectangular, symmetrical layout. After his work for the king, Giuliano returned to Florence with gifts of money, paintings, and sculptures, many of which he gave to Lorenzo as a sign of gratitude. While Giuliano was designing for the king, the king’s son, the Duke of Calabria, also wrote to Lorenzo asking for a palace design. Lorenzo sent a different Giuliano—Giuliano da Maiano—for that task. The Renaissance biographer Giorgio Vasari later wrongly credited Giuliano da Sangallo with the Duke of Calabria’s palace. According to Vasari, after Naples, the Bishop of Ostia (later Pope Julius II) hired Giuliano to refortify his castle in Ostia. Giuliano did work on this project, but alongside another architect.
