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 Janiculum is one of the best locations in Rome for a breathtaking view of the innumerable domes and bell towers that pierce the skyline of the multi-hued architectural museum. Other sights on the Janiculum include the church of San Pietro in Montorio, built upon the site formerly thought to be where St Peter was crucified; the small shrine known as the Tempietto, designed by Donato Bramante, marks the supposed site of Peter's death. The Janiculum also houses a Baroque fountain built by Pope Paul V in the late-17th century, the Fontana dell'Acqua Paola, and several foreign research institutions, including the American Academy in Rome and the Spanish Academy in Rome. The Hill is also 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.
