Method can also help investigate other historical sites around the world, researchers say. Scientists have discovered hidden structures underneath Milan’s fifteenth-century Sforza Castle, hinting at the presence of secret passageways depicted in the drawings of renowned artist and engineer Leonardo da Vinci.
The castle stands today as an emblem of Italian history, long captivating the imaginations of historians, architects, and engineers. It has served as a fortress, residence, and seat of power in Milan since its construction in the 15th century and over the years, countless legends have emerged about its underground chambers.
One of these stories involves the Duke of Milan Ludovico il Moro who allegedly using a secret passageway to visit his wife, Beatrice d’Este. The underground passage was also depicted in the drawings of renowned polymath Leonardo da Vinci. Now, a study applying advanced ground-penetrating radar technology provides fresh evidence that such underground corridors and similar architectural features may indeed exist beneath the castle.
The latest radar survey detected subsurface anomalies beneath the castle suggesting the presence of hidden structures. This technology emits electromagnetic waves into the ground, and by analysing the reflected signals, scientists could identify variations in soil composition, density, and the presence of voids.
