It seems that in the first half of the 15th century the Visconti stayed "in the countryside", a step away from the current Marche metro stop in Milan, in Villa Mirabello. At the time, however, the building we are talking about was called Cascina Mirabello, and it can be found in the documents of 1468 that recognized it as the property of this Pigello Portinari. The Florentine nobleman dear to Prince Sforza, general manager of the annuities of the Milanese duchy and representative of the Florentine House of the Medici in Milan, was also the promoter of the construction of the Portinari Chapel in Sant'Eustorgio.
Towards the end of the 15th century, the villa changed hands, becoming the property of the noble Landriani. Antonio Landriani, awarded by Francesco Sforza as mayor of Milan in 1456, then appointed prefect of the ducal treasury by Galeazzo Maria Sforza, later president of the Mint of Milan by the appointment of Gian Galeazzo Sforza, then became a trusted man and adviser politician of Ludovico il Moro. Ludovico himself was a guest of the Landriani in Villa Mirabello on February 4, 1500. A few years later the villa became one of the houses of the order of the Humiliati, of which Gerolamo Landriani was general. The Landriani family remained the owner of Villa Mirabello for some tens of years, enough to leave traces still visible today in the form of coats of arms that stand out on the fireplace of the main hall and on the ceilings, together with the motto "always el duty ”frescoed on the walls of the villa next to pomegranate figures and blue crosses. It seems that the villa then passed from Landriani to Marino, a rich family of Genoese origin whose member Tommaso entrusted Galeazzo Alessi with nothing less than the construction of Palazzo Marino in Piazza Della Scala.
The history of the villa, in the following years, is rather confused, but it is known that it later became the property of the Serbelloni family and that, starting from the mid-1500s, it faced a sad decline: the building was reduced exclusively to uses agricultural and over the next three centuries it became increasingly dilapidated, until Luca Beltrami, in 1891, considered it by re-evaluating it as an illustrious example of Lombard architectural art. https://www.fondazionevillamirabello.it/
