The Pincian Hill ( PIN-sh(ee-)ən; Italian: Pincio [ˈpintʃo]; Latin: Mons Pincius) is a hill in the northeast quadrant of the historical centre of Rome. The hill lies to the north of the Quirinal, overlooking the Campus Martius. It was outside the original boundaries of the ancient city of Rome, and was not one of the Seven hills of Rome, but it lies within the wall built by Roman Emperor Aurelian between 270 and 273.
