Rome

Rome is the capital city of Italy. It is also the capital of the Lazio region, the centre of the Metropolitan City of Rome, and a special comune named Comune di Roma Capitale. With 2,860,009 residents in 1,285 km², Rome is the country's most populated comune and the third most populous city in the European Union by population within city limits. The Metropolitan City of Rome, with a population of 4,355,725 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, along the shores of the Tiber. Vatican City is an independent country inside the city boundaries of Rome, the only existing example of a country within a city; for this reason, Rome has sometimes been described as the capital of two states. Rome is often referred to as the City of Seven Hills due to its geographic location and also the "Eternal City."
Rome's history spans 28 centuries.
