The hills of the Tuscan hinterland are often explored by those seeking a mix of excitement and unease. Deep within an inextricable thicket on the Monti Pisani, the Mathematician’s Villa is located. Although the forest is slowly reclaiming the land, the echoes of a prestigious past can still be felt.
This historical estate could be defined by many names: the Artist’s Villa or the Partisan’s Villa. However, the name of its owner, Leonida Tonelli, is the one that has ultimately prevailed. Tonelli was not merely an academic; he was a man whose life was defined by both mathematical rigor and civil passion.
Born in 1885, Tonelli was recognized as a prodigy after graduating at the age of 22. Later, a brilliant career was pursued by him across several Italian universities. By 1930, the Department of Mathematics in Pisa was led by him, where the famous Fubini-Tonelli theorem was developed. Furthermore, his bravery was officially recognized when a Bronze Medal for Military Valor was awarded to him during World War I.
During the year 1943, the villa was transformed into a primary residence after Tonelli’s city home was damaged by bombings. Consequently, the estate became a secret headquarters for freedom. As an outspoken anti-fascist, the villa was used by Tonelli to host clandestine meetings of the C.L.N.
In addition, secret weapon caches were hidden among the olive groves by local rebels. It was in this specific location that the Nevilio Casarosa partisan formation was organized. Therefore, the liberation of the Monti Pisani was directly influenced by the activities carried out within these walls.
Currently, the structure is protected by giant thorns and thick vegetation, making access a physical challenge. Once the threshold is crossed, a vision of extraordinary Art Nouveau elegance is revealed. Although the upper floors are considered inaccessible due to structural collapses, the ground floor is still characterized by a haunting beauty.
The rooms are filled with historical artifacts. Old coal stoves, vintage televisions, and faded damask furniture are still found in the main halls. Moreover, the villa is considered a tribute to art; numerous high-quality paintings are scattered throughout the rooms. These works are believed to have been created by Tonelli’s daughter, who inhabited the house until the late 1990s.
Today, the entire complex—including three rural buildings and a vast estate—is offered for sale for one million euros. Handwritten manuscripts containing complex formulas are still stored in the study, waiting to be rediscovered.
If a buyer is not found soon, this concentration of culture and partisan history will be lost. It is feared that the Mathematician’s Villa will eventually be transformed into a pile of forgotten rubble by the relentless passage of time.
