The Janiculum (Gianicolo in Italian) is a hill in western Rome, Italy. Although the second-tallest hill (the tallest being Monte Mario) in the contemporary city of Rome, the Janiculum does not figure among the proverbial Seven Hills of Rome, being west of the Tiber and outside the boundaries of the ancient city. The Hill is the location of the American University of Rome, Pontifical Urban University, and Pontifical North American College, as well as the Orto Botanico dell'Università di Roma "La Sapienza" and the Palazzo Montorio, residence of the Ambassadors of Spain.
