Rome is said to have been built upon seven hills, the first one being Palatine Hill. These hills lie to the east of river Tiber and together form the geographical heart of the eternal city. The hills have played important roles in religion, mythology and politics of ancient Rome. The seven hills are: Aventine Hill, Caelian Hill, Capitoline Hill, Esquiline Hill, Palatine Hill, Quirinal Hill, Viminal Hill. Five of these hills—Aventine, Caelian, Esquiline, Quirinal, and Viminal—are dotted with monuments, buildings and parks. Capitoline, which is located between the Forum and the Campus Martius, is now home to Rome’s city hall, and Palatine Hill, which is the center-most of the Seven Hills, is one of the most ancient parts of the city and belongs to the central archaeological area.
