When the late Pope Francis was elected, a dozen years ago, and famously declined the pomp and perquisites typically associated with the office, among his renunciations was the use of the papal summer residence—a seventeenth-century palazzo in Castel Gandolfo, about fifteen miles south of Rome. Generations of Popes had enjoyed the use of the mansion, which overlooks a volcanic lake and is surrounded by spectacular terraced gardens. The palazzo is now a museum where visitors can admire a gallery of papal portraits, of varying quality, and imagine the dreams that visited the successive occupants of the papal bedroom, with its narrow twin bed. Castel Gandolfo is also home to one of the Holy See's more unexpected institutions: the Vatican Observatory, which since its founding, in 1891, has been dedicated to the scientific study of the heavens.
