In the land survey presented by Tommaso Soderini in 1464 to the ‘O? cials’ of the Land Registry of the Republic of Florence, it was noted that wine and oil were the most highly prized produce of the estate. The construction of the cellars, whose vaulted structure demonstrates their use for wine production, was begun in 1124. In that epoch, the castle belonged to one of the most important banking families of Florence, the Bardi, who, in the second half of the thirteenth century, began the extension of the fortress by building perimeter walls and battlements in the typical Guelph style of the era. The castle remained in the possession of the Bardi until the early part of the 15th century, when it passed to the Soderini family, one of the most politically in? uential families in Florence. It was the Soderini who were responsible for the conversion of the turreted manor house of Gabbiano in Fattoria, already completed by the late 15th century, according to the description in the “land survey” presented in 1480 by the father of Pier Soderini, Tommaso, to the Land Registry “O? cials” of the Land Registry of the Republic of Florence.
