There are apparently three other palaces once associated with the Capponi family: Construction took place in 1702–1717 using designs by Carlo Fontana, and completed by Alessandro Cecchini.
The palace was commissioned by the marchese Alessandro Capponi, on the street then called via San Sebastiano.
The Gardens were commissioned in 1740 by the sons of Capponi (Scipione and Francesco Maria).
Subsequently, the palace came to be owned in 1920 by the art collector Egisto Paolo Fabbri.
The interior has a theatrical entry staircase in pietra serena with a ceiling frescoed with an Allegory of Triumph.
