[1] In 1818 the property was purchased, for the price of 27,000 gold piastres,[2] by Maria Letizia Ramolino, mother of the French Emperor Napoleon Bonaparte, who lived there until her death in 1836.

The heirs, the Bonaparte princes of Canino and Musignano, sold it in 1905 to the Marquises Misciatelli, while from 1972 it passed to the insurance company INA Assitalia, later acquired by Assicurazioni Generali in 2013.

Between 2017 and 2019, through the Valore e Cultura programme, Arthemisia, a company active in the field of exhibition organisation, set up its headquarters there following restoration and redevelopment of the building.

The main floor is punctuated by five windows with curved tympanums decorated with shells, while the central one is surmounted by the coat of arms of the Bonapartes of Canino supported by an eagle.

The well-known covered corner balcony, called mignano or bussolotto, is not present in a 1675 print by Giovanni Battista Falda, thus representing a later addition.
