A remarkable discovery beneath Milan’s historic Sforza Castle has reignited discussions about Leonardo da Vinci’s influence on Renaissance military architecture. Researchers from the Politecnico di Milano have identified underground passageways that closely resemble those depicted in a sketch by Leonardo from around 1495. The findings suggest that these tunnels, which had long been speculated about based on historical records, were likely intended for defensive military use during times of siege. This revelation sheds new light on the hidden history beneath one of Italy’s most famous medieval landmarks.
The research, conducted between 2021 and 2023, utilized advanced ground-penetrating radar and laser scanning technology to digitally map the underground structures. Initially, the team aimed to document the well-known subterranean passage beneath the Ghirlanda, the outer defensive wall of the castle. However, their survey unexpectedly revealed a second, secret tunnel running parallel to the first, just three feet beneath the surface. Experts believe this passageway was a concealed route for soldiers, allowing them to move undetected and defend the fortress from within.
Leonardo da Vinci, widely recognized for his contributions to art and science, was also a visionary in military engineering. While his exact role in the construction of these passageways remains uncertain, the discovery reinforces his deep connection to the architectural evolution of the Sforza Castle. Commissioned by Duke Ludovico Sforza in the late 1400s, Leonardo spent considerable time at the castle, designing defensive structures, weapons, and even contributing to the property’s artistic embellishments. His sketches, now linked to these tunnels, reveal his strategic approach to fortification and warfare.
In addition to the military passageways, researchers detected tunnels leading towards the Basilica of Santa Maria delle Grazie, where Ludovico Sforza’s wife is buried. Historical records suggest that the grief-stricken duke may have commissioned this tunnel for private access to the basilica. The newly discovered underground rooms further indicate the presence of additional, as yet unexplored, subsurface structures. Given that the original castle complex was nearly six times larger than its present-day footprint, researchers suspect that much more remains hidden beneath the surface.
The Sforza Castle has undergone significant transformations over the centuries, including extensive demolitions during the Napoleonic wars and restoration efforts in the late 19th century. Despite these changes, the recent findings prove that crucial remnants of the past still survive underground. The discovery underscores the importance of using modern technology to explore historical sites without invasive excavation, preserving valuable cultural heritage while unlocking secrets from centuries past.
Leonardo’s influence on Renaissance architecture extended beyond theoretical designs. His sketches often served as conceptual blueprints, inspiring advancements in structural engineering. While some of his architectural ideas remained hypothetical, the striking resemblance between his drawings and the Sforza Castle’s underground tunnels raises compelling questions about his direct involvement in their creation. Further investigation is required to determine the extent of his contribution, but the discovery undeniably strengthens his legacy as a pioneer of military strategy and defensive engineering.
As technology continues to uncover hidden layers of history, this finding highlights the significance of preserving cultural and architectural heritage. The tunnels beneath Sforza Castle serve as a testament to the ingenuity of the Renaissance era and the enduring impact of Leonardo da Vinci’s genius. With ongoing research and technological advancements, more groundbreaking discoveries may still be waiting beneath the surface, offering invaluable insights into the past.
