Rome is a city and special comune ("Roma Capitale") in Italy. Rome is the capital of Italy and the capital of Lazio (Latin: Latium). With 2.8 million residents in 1,285.3 km (496.3 sq mi), it is also the country's largest and most populated comune and fourth-most populous city in the European Union by population within city limits. Between 3.2 and 3.8 million people live in the Rome urban and metropolitan area. The city is located in the central-western portion of the Italian Peninsula, on the Tiber River within the Lazio region of Italy. Rome is referred to as "The Eternal City," a notion expressed by ancient Roman poets and writers.
Rome's history spans more than two and a half thousand years, since its founding in 753 BC, when it was built over the remains of an even older Late Neolithic village. It was the capital city of the Roman Kingdom, the Roman Republic and the Roman Empire, which was the dominant power in Western Europe and the lands bordering the Mediterranean for over seven hundred years from the 1st century BC until the 7th century AD and the city is regarded as one of the birthplaces of western civilization. Since the 1st century AD Rome has been the seat of the Papacy and, after the end of Byzantine domination, in the 8th century it became the capital of the Papal States, which lasted until 1870. In 1871 Rome became the capital of the Kingdom of Italy, and in 1946 that of the Italian Republic.
After the Middle Ages, Rome was ruled by popes such as Alexander VI and Leo X, who transformed the city into one of the major centers of the Italian Renaissance, along with Florence. The current version of St Peter's Basilica was built and the Sistine Chapel was painted by Michelangelo. Famous artists and architects, such as Bramante, Bernini and Raphael resided for some time in Rome, contributing to its Renaissance and Baroque architecture.
Rome has been ranked by GaWC in 2010 as a beta+ world city, as well as the 28th most important
