Palazzo Falconieri

it.wikipedia dates the house to about 1515, built for the Ceci family; Roma Capitale dates the building to 1576, under the Odescalchi. The Ceci sold it in 1574 to the Odescalchi, who sold it in 1606 to the Farnese, and in 1638 it went to Orazio Falconieri for 16,000 scudi. Borromini enlarged it between 1646 and 1649, taking the front from eight window-bays to eleven and adding a matching blind portal carrying the Falconieri falcon. Roman river-port remains survive under the building. Napoleon's mother Maria Letizia Ramolino lived here from 1815 to 1818, her half-brother Cardinal Fesch being the resident. The palace was sold to the Medici del Vascello in 1865, altered on the river side in 1890 for the lungotevere, then bought by Vilmos Frankoi and ceded to the Hungarian state in 1927. it.wikipedia gives the Accademia d'Ungheria's foundation as 1927; Roma Capitale says it has been seated in the palace since 1928.
