2 Best Sights in Side Trips from Rome, Italy

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, which sits just at the end of Ariccia's famous bridge, for most of the interior scenes in his 1963 film The Leopard. The rooms of the piano nobile (main floor)—which, unlike Rome's Palazzo Chigi, are open to the public, but only 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 showcases portraits of 10 Chigi sisters, all of whom took the veil. You can get a close look (with a guide) at Le Stanze del Cardinale (Cardinal's Rooms), the suites occupied by the pleasure-loving Cardinal Flavio Chigi.

Directly across from Palazzo Chigi is the Church of the Assumption, with its distinctive blue dome and round shape designed by none other than Gian Lorenzo Bernini. The artistic architect had his best students execute most of the work of building and decorating the Pantheon-inspired church, creating porticoes outside and an elaborately plastered cupola inside, which steals the show in the otherwise simple interior.
