Tivoli, the old "Tibur Superbum" as Virgilio called it, is in the western side of the Monti Sabini, small mountains in the East of Rome. It's 235 meters over the sea and it lays in a hill, for this reason Orazio called it "Tibur supinum". The geographical position makes the town a regular transit point, once the only one, to go from the Roman country to the Appennine and the Adriatic sea.
