This is a true rarity—a baroque residence whose original furniture, paintings, drapes, and decorations are largely intact. The Italian film director Luchino Visconti used the villa for most of the interior scenes in his 1963 film The Leopard. The rooms of the piano nobile (main floor), which like the rest of the palazzo's sections that are open to the public can only be viewed on guided tours, contain intricately carved pieces of 17th-century furniture, as well as textiles and costumes from the 16th to the 20th century. The Room of Beauties is lined with paintings of the loveliest ladies of the day, and the Nuns' Room with portraits of 10 Chigi sisters, all of whom took the veil.
Open for touring only on weekends are Le stanze del Cardinale (Cardinal's Rooms), suites occupied by the pleasure-loving Cardinal Flavio Chigi. The upper floors contain the Museo del Barocco (Baroque Museum), with an important collection of 17th-century paintings. The park stretching behind the palace is the last remnant of the ancient Latium forest, where herds of deer still graze under the trees. Tours in English are possible if you book ahead.
