As per Vasari, Palazzo Pitti (Pitti Palace) was designed by Brunelleschi despite the fact that it has not been proven. The development of this impressive structure was finished during the second 50% of the fifteenth century. This work authorized by the Florentine dealer Luca Pitti, companion and partner of Cosimo de Medici, was made by Brunelleschi's disciple, Luca Fancelli. Luca Pitti needed his living arrangement to be the most forcing in the city. With the eradication of the Medici, the duchy and the castle passed to the hands of the Lorraine house and during the nineteenth century Napoleon utilized it as a living arrangement during his standard in Italy.
