Fourteenth-fourteenth-century Venetian-Gothic style building.

The palace dates back to the 15th century and was the residence of the Barbarigo family of which its greatest exponent was "Doge Agostino Barbarigo." The Palace was part of the dowry that Elena Barbarigo, daughter of Doge Agostino, brought to her husband Giorgio Nani, and from him it passed to his son Bernardo, progenitor of the branch of the family known as "di San Trovaso."

In the eighteenth century, the Palace was home to the "Museo Naniano" (Museum of Antiquities belonging to the private collection of the Nani Family), while later it was home to the Cà Foscari University of Venice and the "Glass Museum Vitraria" then.

The palace, in perfect Gothic style, where the restoration of the facade was supervised by Sansovino, collects important frescoes such as that by Guarana, a collaborator of Tiepolo, and important stuccoes by Alessandro Vittoria.
