Giuliano da Sangallo was a famous Italian builder from the Renaissance. 

Lorenzo de' Medici became Giuliano's patron. A patron is someone who pays an artist to do important work. Giuliano designed many special things for the Medici family. He built a country home called the Medici Villa at Poggio a Caiano. Construction on this villa began in 1485. It used classical styles like Ionic columns. He also designed a church called Santa Maria delle Carceri in Prato. This church was meant to mark a place where a miracle was seen. The church uses a Greek cross plan with four equal arms. 
Giuliano was also very good at military work. Lorenzo asked him to build defenses in the town of Castellina. He had to manage artillery to stop an invasion by the Duke of Calabria. Giuliano was successful and helped push the forces away. This victory gave Lorenzo even more trust in him. Later, Giuliano was sent to Naples to design a castle for King Ferrante of Aragon. This was a way for the Medici family to share their culture. The king's son even asked for a palace design too.
Giuliano's life was full of many big projects. He designed the Palazzo Gondi for a wealthy banker in Florence. He also worked on a large palace in Savona for a man named Giuliano della Rovere. This palace was meant to be very big and imposing. Toward the end of his life, he helped with St. Peter's Basilica in Rome. He even helped Michelangelo with the Sistine Chapel ceiling. However, he was too old to lead the big building projects in his final years. He died in Florence in 1516. 
Many of Giuliano's buildings were never fully finished. Some were destroyed, like the Church of San Gallo. Because of this, his most important treasure is his Sienese Sketchbook. This book shows his many ideas for domes and sculptures. It also has technical drawings and measurements. His sketches show he studied both old and new styles of building. Even without finished walls, his ideas helped shape the world of art. He left a legacy of great thought and skill.
Giuliano da Sangallo was a highly influential Italian architect, sculptor, and military engineer. 
To prepare for his career, Giuliano studied the works of famous predecessors. He looked closely at the designs of Leon Battista Alberti and Filippo Brunelleschi. These studies helped him master classical design and develop a creative eye. He also learned how to manage military fortifications and artillery. This skill was tested when Lorenzo called him to defend the town of Castellina. Giuliano managed the artillery to successfully push out invading forces from the Duke of Calabria. This victory proved his talent for both construction and military strategy.
Lorenzo de' Medici became Giuliano's primary patron, providing him with many major commissions. One of his most famous works is the Medici Villa at Poggio a Caiano. 

Giuliano's work also served important political purposes through diplomacy. In 1488, he was commissioned to design a castle for Ferrante of Aragon, the King of Naples. Sending a talented architect like Giuliano was a way for the Medici family to export Florentine culture. Although the castle was never built, his detailed sketches still exist. The plan featured a rectangular, symmetrical axis and a portico between two stairways. This design shared many similarities with his earlier work on the Medici Villa. These architectural gifts helped maintain peace and good faith between different Italian city-states.
In Florence, Giuliano worked on several other important structures. He designed the Church of San Gallo for Augustinian monks around 1488. 

As his career progressed, Giuliano worked for powerful religious leaders. He helped renovate a castle in Ostia alongside the architect Baccio Pontelli. Later, while in exile, he designed the Palazzo della Rovere in Savona for Giuliano della Rovere. This palace used a towering façade to make the building appear more imposing. In his final years, he was involved with the construction of St. Peter's Basilica in Rome. He even assisted Michelangelo by helping to remove mould from the Sistine Chapel ceiling. However, he was too old to lead the massive basilica project after the death of Pope Julius II.
Giuliano da Sangallo died in Florence in 1516. His physical legacy is unique because many of his buildings are unfinished or were destroyed. For example, the Church of San Gallo was destroyed during the Siege of Florence in 1529. Instead, his lasting impact is found in his intellectual contributions. The Sienese Sketchbook provides a detailed look into his creative mind. It contains technical drawings, measurements, and ideas for everything from cathedral domes to new artillery. These sketches show his deep interest in both medieval and classical architecture, ensuring his influence survived through his ideas.
