Upon the bishop's death, Palazzo del Vescovo was put up for auction together with the vast agricultural properties following the Italian law on Ecclesiastical Assets and purchased on 16 September 1868 by Countess Eva Bernini Cerretani. On 31 December 1877, Countess Cerretani sold the entire estate to the Ciacci family based in Castelnuovo dell'Abate, Siena. Following the marriage in the first half of the 20th century between Count Alberto Piccolomini d'Aragona, a descendant of Enea Silvio Piccolomini known as Pope Pius II, and Miss Elda Ciacci, Palazzo del Vescovo became Palazzo Ciacci Piccolomini d'Aragona.
In 1985, with the extinction of the family line, Giuseppe Bianchini took over the property. Giuseppe Bianchini, who had already worked in the estate for many years, applied a new and avant-garde production philosophy for those years, developing and increasing production, wine quality and opening up the export of our products to the world. Unfortunately, Giuseppe passed away in February 2004, leaving the task of continuing his work to his children Paolo and Lucia.
