The Janiculum (/dʒəˈnɪkjᵿləm/; Italian:Gianicolo, pronounced [dʒaˈniːkolo]) 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.
