Unearthing History: The Discovery
Researchers have confirmed the existence of secret tunnels beneath Milan’s Sforza Castle, structures initially documented in a 1495 sketch by Leonardo da Vinci. These tunnels, long relegated to the realm of medieval lore, have now been located and mapped using ground-penetrating radar.
This groundbreaking discovery unveils at least 40,000 square meters of hidden constructions beneath the castle grounds.
Francesca Biolo, the lead researcher, told CNN that the team was able to locate the secret passages under the exterior walls.

A Castle’s Evolution and da Vinci’s Role
Construction of the castle began in 1358, but it faced destruction a century later. In 1450, Francesco Sforza, the Duke of Milan, initiated its reconstruction. the renovation continued under his son, Ludovico, known as “the Moor.” During this period, leonardo da Vinci was commissioned to enhance parts of the structure, including the Sala delle Asse, were restoration of his frescoes is ongoing.
Da Vinci frequented the castle in the late 15th century and is believed to have documented the secret passages built beneath the Ghirlanda.Prior to the recent work, scientists could only speculate about their existence based on Da Vinci’s sketches.
More Than Military Tunnels
In addition to the military tunnels, researchers discovered small underground rooms and a passage believed to have been commissioned by Ludovico to connect the castle to the Basilica of Santa Maria delle Grazie, where his wife, Beatrice D’Este, was buried.
Further inquiry is needed to confirm this hypothesis,according to Francesca Biolo.
The team is working to create a digital copy of the Sforza Castle.
Franco Guzzeti, a professor of geomatics, stated, “The objective is to create a digital copy of the Castelo Sforza, a model that can show the current aspect of the castle and also allow to explore the past, revealing the ancestral structures that are no longer visible.”
Da Vinci’s Contribution: Architect or Enhancer?
the extent of Da Vinci’s involvement in the architectural design and execution remains uncertain. While his drawings were crucial to the discoveries, it is more likely that Da Vinci enhanced existing tunnels within the castle.
Francesca Fiorani, an art history professor, who was not involved in the Milan research, suggests further investigation is needed to confirm if the drawings and the newly discovered tunnels are the same.

Frequently asked Questions about the Sforza Castle Tunnels
What are the Sforza Castle tunnels,and where are they located?
The sforza Castle tunnels are a network of secret passages and underground rooms located beneath Sforza Castle in
milan,italy. Recent archaeological work confirmed their existence after being hinted at by Leonardo da Vinci’s
sketches.
How were the Sforza Castle tunnels discovered?
The tunnels were discovered and mapped using ground-penetrating radar. This technology allowed researchers to
locate the hidden constructions without excavation.
Who documented the tunnels initially?
Leonardo da Vinci documented the existence of these tunnels in a sketch dating back to 1495. This sketch provided
the initial clue for researchers to begin their search.
How large is the discovered tunnel network?
The discovered hidden constructions beneath the castle grounds span at least 40,000 square meters.
What was Leonardo da Vinci’s role at Sforza Castle?
Leonardo da Vinci was commissioned to enhance parts of the castle during the late 15th century. His work
included contributions to the Sala delle Asse, where restoration of his frescoes is ongoing. he also documented
the secret passages beneath the Ghirlanda.
Were the tunnels used for military purposes?
Yes, in addition to other uses, the tunnels served a military purpose. Researchers discovered military tunnels
along with small underground rooms.
Is there a rumored tunnel connecting the castle to the Basilica of Santa Maria delle Grazie?
Researchers discovered a passage believed to have been commissioned by Ludovico Sforza to connect the castle to
the Basilica of Santa Maria delle Grazie, where his wife, Beatrice D’Este, was buried. Further inquiry is needed
to confirm this hypothesis.
What is the purpose of creating a digital copy of Sforza Castle?
The objective is to create a digital copy of the Castelo Sforza, a model that can show the current aspect of the
castle and also allow exploration of the past, revealing the ancestral structures that are no longer visible.
was Da Vinci the architect of the tunnels, or did he enhance existing ones?
It is more likely that Da Vinci enhanced existing tunnels within the castle rather than designing and executing the
architectural design from scratch.
How did the Sforza family influence the castle’s construction and Da Vinci’s Involvement?
Construction of the castle began in 1358, but it faced destruction a century later. In 1450, Francesco Sforza, the Duke of Milan, initiated its reconstruction.The renovation continued under his son, Ludovico, known as “the Moor,” who commissioned Leonardo da Vinci to enhance parts of the structure.
What challenges do researchers face in confirming the purpose and origins of the tunnels?
According to Francesca Fiorani, an art history professor, further investigation is needed to confirm if Da Vinci’s drawings and the newly discovered tunnels align.
Are the Sforza Castle tunnels open to the public?
Currently there is no information to determine if the Sforza Castle tunnels are open to the public, though, it’s likely tours will become available as digital copies of the castle are developed.
