Monuments and places of interest
The Apostolic Palace of Castel Gandolfo (Palazzo Apostolico di Castel Gandolfo in Italian), the Pope's summer residence, is a 17th century building designed by Carlo Maderno for Pope Urban VIII. The papal palace, and the adjoining Villa Barberini that was added to the complex by Pius XI have enjoyed extraterritorial rights since the signature of the 1929 treaty with Italy; the little piazza directly in front was renamed Piazza della Libertà in the first flush of Italian unity after 1870. The Papal Palace remained unused from 1870 until 1929. Popes Pius XII (1958) and Paul VI (1978) died at CastelGandolfo.

As part of its extensive formal gardens is located, on the existing remains of the complex built by the Roman Emperor Domitian.
