Rome, Italy

Rome is the capital city of Italy and a special comune (named Comune di Roma Capitale). Rome also serves as the capital of the Lazio region. With 2,868,782 residents in 1,285 km2 (496.1 sq mi), it is also the country’s most populated comune. It is the fourth-most populous city in the European Union by population within city limits. It is the centre of the Metropolitan City of Rome, which has a population of 4.3 million residents. Rome is located in the central-western portion of the Italian Peninsula, within Lazio (Latium), along the shores of the Tiber. The Vatican City (the smallest country in the world) 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 been often defined as capital of two states.

Rome has the status of a global city. In 2016, Rome ranked as the 14th-most-visited city in the world, 3rd most visited in the European Union, and the most popular tourist attraction in Italy. Its historic centre is listed by UNESCO as a World Heritage Site. Monuments and museums such as the Vatican Museums and the Colosseum are among the world’s most visited tourist destinations with both locations receiving millions of tourists a year, and the city hosted the 1960 Summer Olympics. Rome is the seat of several specialized agencies of the United Nations, such as the Food and Agriculture Organization (FAO), the World Food Programme (WFP) and the International Fund for Agricultural Development (IFAD). The city hosts the headquarters of many international business companies, such as Eni, Enel, TIM, Leonardo S.p.A., and national and international banks such as Unicredit and BNL. Its business district, called EUR, is the base of many companies involved in the oil industry, the pharmaceutical industry, and financial services. Rome is also an important fashion and design centre thanks to renowned international brands centered in the city. Rome’s Cinecittà Studios have been the set of many Academy Award–winning movies.

Rome is in the Lazio region of central Italy on the Tiber river. The original settlement developed on hills that faced onto a ford beside the Tiber Island, the only natural ford of the river in this area. The Rome of the Kings was built on seven hills: the Aventine Hill, the Caelian Hill, the Capitoline Hill, the Esquiline Hill, the Palatine Hill, the Quirinal Hill, and the Viminal Hill. Modern Rome is also crossed by another river, the Aniene, which flows into the Tiber north of the historic centre.

Although the city centre is about 24 kilometres (15 mi) inland from the Tyrrhenian Sea, the city territory extends to the shore, where the south-western district of Ostia is located. The altitude of the central part of Rome ranges from 13 metres (43 ft) above sea level (at the base of the Pantheon) to 139 metres (456 ft) above sea level (the peak of Monte Mario).[62] The Comune of Rome covers an overall area of about 1,285 square kilometres (496 sq mi), including many green areas.

Rome has a Mediterranean climate, with cool, humid winters and warm, dry summers.

Its average annual temperature is above 20 °C (68 °F) during the day and 10 °C (50 °F) at night. In the coldest month, January, the average temperature is 12 °C (54 °F) during the day and 3 °C (37 °F) at night. In the warmest months, July and August, the average temperature is 30 °C (86 °F) during the day and 18 °C (64 °F) at night.

As the capital of Italy, Rome hosts all the principal institutions of the nation, including the Presidency of the Republic, the government (and its single Ministeri), the Parliament, the main judicial Courts, and the diplomatic representatives of all the countries for the states of Italy and Vatican City. Many international institutions are located in Rome, notably cultural and scientific ones, such as the American Institute, the British School, the French Academy, the Scandinavian Institutes, and the German Archaeological Institute. There are also specialised agencies of the United Nations, such as the FAO. Rome also hosts major international and worldwide political and cultural organisations, such as the International Fund for Agricultural Development (IFAD), World Food Programme (WFP), the NATO Defence College and the International Centre for the Study of the Preservation and Restoration of Cultural Property (ICCROM).

Although the economy of Rome is characterised by the absence of heavy industry and it is largely dominated by services, high-technology companies (IT, aerospace, defence, telecommunications), research, construction and commercial activities (especially banking), and the huge development of tourism are very dynamic and extremely important to its economy. Rome’s international airport, Fiumicino, is the largest in Italy, and the city hosts the head offices of the vast majority of the major Italian companies, as well as the headquarters of three of the world’s 100 largest companies: Enel, Eni, and Telecom Italia.

Universities, national radio and television and the movie industry in Rome are also important parts of the economy: Rome is also the hub of the Italian film industry, thanks to the Cinecittà studios, working since the 1930s. The city is also a centre for banking and insurance as well as electronics, energy, transport, and aerospace industries. Numerous international companies and agencies headquarters, government ministries, conference centres, sports venues, and museums are located in Rome’s principal business districts: the Esposizione Universale Roma (EUR); the Torrino (further south from the EUR); the Magliana; the Parco de’ Medici-Laurentina and the so-called Tiburtina-valley along the ancient Via Tiburtina.

Rome is at the centre of the radial network of roads that roughly follow the lines of the ancient Roman roads which began at the Capitoline Hill and connected Rome with its empire. Today Rome is circled, at a distance of about 10 km (6 mi) from the Capitol, by the ring-road (the Grande Raccordo Anulare or GRA).

Due to its location in the centre of the Italian peninsula, Rome is the principal railway node for central Italy. Rome’s main railway station, Termini, is one of the largest railway stations in Europe and the most heavily used in Italy, with around 400 thousand travellers passing through every day. The second-largest station in the city, Roma Tiburtina, has been redeveloped as a high-speed rail terminus. As well as frequent high speed day trains to all major Italian cities, Rome is linked nightly by ‘boat train’ sleeper services to Sicily, and internationally by overnight sleeper services to Munich and Vienna by ÖBB Austrian railways.

Among the global cities, Rome is unique in having two sovereign entities located entirely within its city limits, the Holy See, represented by the Vatican City State, and the territorially smaller Sovereign Military Order of Malta. The Vatican is an enclave of the Italian capital city and a sovereign possession of the Holy See, which is the Diocese of Rome and the supreme government of the Roman Catholic Church. Rome therefore hosts foreign embassies to the Italian government, to the Holy See, to the Order of Malta and to certain international organizations. Several international Roman Colleges and Pontifical Universities are located in Rome.
