Recent explorations beneath the 575-year-old Sforza Castle in Milan, Italy, have unveiled a network of secret military tunnels.

Newsweek is writing that these passages, some of which were previously known only through historical documents, played crucial roles in the castle's defense strategies.

Historical significance of Sforza Castle

Sforza Castle (Castello Sforzesco) in Milan, Italy, was built in 1450 by Duke Francesco Sforza on the ruins of a 14th-century fortification. Initially a military fortress, it became a residence for the Sforza family, one of Renaissance Italy's most influential dynasties. Over centuries, the castle underwent various transformations, including significant renovations by artists like Leonardo da Vinci, who contributed to its design and decorations. After suffering damage during World War II, it was restored and now houses museums, art collections, and historic archives, making it a centerpiece of Milan’s cultural and historical heritage.

The secret tunnels

Among the tunnels discovered is a passage believed to have been used by a duke to secretly visit the tomb of his beloved wife, a route hinted at in plans by Leonardo da Vinci.

These tunnels not only highlight the castle's architectural ingenuity but also its strategic importance during tumultuous periods in Milan's history.

Architectural features

The castle's design reflects the military architecture of the Renaissance period, featuring massive walls, battlements, and a moat. The recent discoveries of the tunnels add another layer to its complex structure, showcasing advanced engineering techniques of the time.

Preservation and public Access

Efforts are underway to preserve these newly discovered tunnels. Once deemed safe, they may be opened to the public, offering visitors a unique glimpse into the castle's hidden past and enhancing our understanding of Milan's rich historical tapestry.

The unveiling of these secret tunnels not only sheds light on the clandestine activities that took place within Sforza Castle but also underscores the importance of ongoing archaeological efforts in uncovering and preserving historical sites.
