Sebastiano Ximenes

Sebastiano Ximenes was an Italian banker of Portuguese origin in Florence, and noted patron of the Arts. He bought and later renamed the Florentine palace, Palazzo Ximenes [de Sangallo] -- still a tourist attraction today.

Legacy

Sebastiano Ximenes had bought the castle of Sammezzano from Giovanni Jacopo de' Medici. The castle remained in the Ximenes family until the family line died out in 1816.
This particular Ximenes line died out in Italy in 1816, though the name survives in Florence.
