Later, in the early 4th century BC, the Servian Walls were constructed to protect the seven hills. The city of Rome, thus, came into being as these separate settlements acted as a group, draining the marshy valleys between them and turning them into markets ( fora in Latin). The seven hills' denizens began to interact, which began to bond the groups. Tradition holds that Romulus and Remus founded the original city on the Palatine Hill on 21 April 753 BC, and that the seven hills were first occupied by small settlements that were not grouped. These are sometimes confused with the traditional seven hills.


These were the Oppius, Palatium, Velia, Fagutal, Cermalus, Caelius, and Cispius. Separate also are the seven hills associated with the Septimontium, a proto-urban festival celebrated by the residents of the seven communities associated with the hills or peaks of Rome. The Vatican Hill (Latin Collis Vaticanus) lying northwest of the Tiber, the Pincian Hill ( Mons Pincius), lying to the north, the Janiculan Hill (Latin Janiculum), lying to the west, and the Sacred Mount (Latin Mons Sacer), lying to the northeast, are not counted among the traditional Seven Hills, being outside the boundaries of the most ancient part of Rome.
