Seven hills of Rome in the context of "Quirinal Palace"

Rome is the capital city and most populated comune (municipality) of Italy. It is also the administrative centre of the Lazio region and of the Metropolitan City of Rome. A special comune named Roma Capitale with 2,746,984 residents in 1,287.36 km (497.1 sq mi), Rome is the third most populous city in the European Union by population within city limits. The Metropolitan City of Rome Capital, with a population of 4,223,885 residents, is the most populous metropolitan city in Italy. Its metropolitan area is the third-most populous within Italy. Rome is located in the central-western portion of the Italian Peninsula, within Lazio (Latium), along the shores of the Tiber Valley. Vatican City (the smallest country in the world and headquarters of the worldwide Catholic Church under the governance of the Holy See) is an independent country inside the city boundaries of Rome, the only existing example of a country within a city. Rome is often referred to as the City of Seven Hills due to its geography, and also as the "Eternal City". Rome is generally considered to be one of the cradles of Western civilization and Western Christian culture, and the centre of the Catholic Church.

Rome's history spans 28 centuries. While Roman mythology dates the founding of Rome at around 753 BC, the site has been inhabited for much longer, making it a major human settlement for over three millennia and one of the oldest continuously occupied cities in Europe. The city's early population originated from a mix of Latins, Etruscans, and Sabines. Eventually, the city successively became the capital of the Roman Kingdom, the Roman Republic and the Roman Empire, and is regarded by many as the first-ever Imperial city and metropolis. It was first called The Eternal City (Latin: Urbs Aeterna; Italian: La Città Eterna) by the Roman poet Tibullus in the 1st century BC, and the expression was also taken up by Ovid, Virgil, and Livy. Rome is also called Caput Mundi (Capital of the World).

The culture of ancient Rome existed throughout the almost 1,200-year history of the civilization of Ancient Rome. The term refers to the culture of the Roman Republic, later the Roman Empire, which at its peak covered an area from present-day Lowland Scotland and Morocco to the Euphrates.

Life in ancient Rome revolved around the city of Rome, its famed seven hills, and its monumental architecture such as the Colosseum, Trajan's Forum, and the Pantheon. The city also had several theaters and gymnasia, along with many taverns, baths and brothels. Throughout the territory under ancient Rome's control, residential architecture ranged from very modest houses to country villas, and in the capital city of Rome, there were imperial residences on the elegant Palatine Hill, from which the word palace is derived. The vast majority of Rome's population lived in the city center, packed into Insulae (apartment blocks).

The Palatine Hill (/ˈpælətaɪn/; Classical Latin: Palatium; Neo-Latin: Collis/Mons Palatinus; Italian: Palatino [palaˈtiːno]), which relative to the seven hills of Rome is the centremost, is one of the most ancient parts of the city; it has been called "the first nucleus of the Roman Empire". The site is now mainly a large open-air museum whilst the Palatine Museum houses many finds from the excavations here and from other ancient Italian sites.

Imperial palaces were built there, starting with Augustus. Before imperial times the hill was mostly occupied by the houses of the rich.

The Capitolium or Capitoline Hill (/ˈkæpɪtəlaɪn, kəˈpɪt-/ KAP-it-ə-lyne, kə-PIT-; Italian: Campidoglio [kampiˈdɔʎʎo]; Latin: Mons Capitolinus [ˈmõːs kapɪtoːˈliːnʊs]), between the Forum and the Campus Martius, is one of the Seven Hills of Rome.

Vatican Hill (/ˈvætɪkən/; Latin: Mons Vaticanus; Italian: Colle Vaticano) is a hill in Rome, located on the right bank (west side) of Tiber river, opposite to the traditional seven hills of Rome. The hill also gave the name to Vatican City. It is the location of St. Peter's Basilica.

The Oppian Hill (Latin, Oppius Mons; Italian: Colle Oppio) is the southern spur of the Esquiline Hill, one of the Seven hills of Rome, Italy. It is separated from the Cispius on the north by the valley of the Suburra, and from the Caelian Hill on the south by the valley of the Colosseum. The Oppius and the Cispius together form the Esquiline plateau just inside the line of the Servian Wall.

In the divisions of the Septimontium (seven hills) Fagutal appears as an independent locality, which implies that originally "Oppius" was strictly applied to this spur except the western end. The northern tip of this western end was also called Carinae, which extended between the Velian Hill and the Clivus Pullius, looked out to the southwest (across the swamps of the Palus Ceroliae towards the Aventine), incorporated the Fagutal and was one of ancient Rome's most exclusive neighborhoods.
