The event "Il Giardino Ritrovato, that during summer hosts a series of "art talks", concerts and performances, is part of this requalification.
The fountains that decorates the center of the garden depicts "The Marriage of Venice and the Sea":
The piece is the job of Carlo Monaldi, a commission during the times where the palace hosted the Embassy of the Republic of Venice in Rome.
It was later restored by Giovanni Prini, who added the other statues around the main piece on 1930.
