The Palazzo Gianfigliazzi Bonaparte was built in the mid-15th century on the right bank of the Arno, initiated by the Teghiacci, a family of Sienese merchants established in Florence. At a time when the neighborhood's residences still stood back from the river, it was one of the first to rise directly along the banks. The construction was unfinished when the building was sold in 1460 to the Gianfigliazzi, a prominent banking family established near Santa Trinita since the 13th century. Bongianni Gianfigliazzi, a merchant and diplomat, completed its development: the façade, rendered and adorned with sgraffito, is crowned with a loggia opening onto the Arno. His descendants would live there until the extinction of the family's direct line at the end of the 18th century.
In 1827, the writer Alessandro Manzoni stayed there for a month, an event commemorated today by a plaque on the façade. The following year, in 1828, the palace was acquired by Louis Bonaparte, brother of Napoleon I and former King of Holland, who was then in exile in Florence. In 1867, the property passed to the Belgian baron Adrien van der Linden d’Hooghvorst, who had the façade remodeled in a Neo-Renaissance style and added the central balcony. Florence was then the capital of the Kingdom of Italy, and the palace's salons became the setting for numerous balls and receptions. Acquired in 1920 by Aldemiro Campodonico, who had it raised by an extra floor, the palace still belongs to his descendants today.
