Temple of Saturn
Between 1802 and 1806 Valadier turned the main building into a palace, and transformed other buildings. He also laid out the park with symmetrical avenues around the palace. Numerous works of classical art, many of which were sculptures, were purchased to furnish the palace. Following the death of Giovanni, Alessandro commissioned the painter and architect Giovan Battisti Caretti in 1832 to further develop the property. In addition to expanding the buildings, Caretti constructed several buildings in the park. These included the False Ruins, the Temple of Saturn, and the Tribuna con Fontana.
