Rome (Italian and Latin: Roma [ˈroːma] (listen)) 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 (496.1 sq mi),[2] 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.[3] Its metropolitan area is the third-most populous within Italy.[4] Rome is located in the central-western portion of the Italian Peninsula, within Lazio (Latium), along the shores of the Tiber. Vatican City (the smallest country in the world)[5] 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 geographic location, and also as the “Eternal City”.[6] Rome is generally considered to be the “cradle of Western civilization and Christian culture”, and the centre of the Catholic Church.
Rome’s architecture over the centuries has greatly developed, especially from the Classical and Imperial Roman styles to modern fascist architecture. Rome was for a period one of the world’s main epicentres of classical architecture, developing new forms such as the arch, the dome and the vault. The Romanesque style in the 11th, 12th, and 13th centuries was also widely used in Roman architecture, and later the city became one of the main centres of Renaissance, Baroque and neoclassical architecture.
Public parks and nature reserves cover a large area in Rome, and the city has one of the largest areas of green space among European capitals. The most notable part of this green space is represented by the large number of villas and landscaped gardens created by the Italian aristocracy. While most of the parks surrounding the villas were destroyed during the building boom of the late 19th century, some of them remain. The most notable of these are the Villa Borghese, Villa Ada, and Villa Doria Pamphili. Villa Doria Pamphili is west of the Gianicolo hill, comprising some 1.8 km2 (0.7 sq mi). The Villa Sciarra is on the hill, with playgrounds for children and shaded walking areas. In the nearby area of Trastevere, the Orto Botanico (Botanical Garden) is a cool and shady green space. The old Roman hippodrome (Circus Maximus) is another large green space: it has few trees but is overlooked by the Palatine and the Rose Garden (‘roseto comunale’). Nearby is the lush Villa Celimontana, close to the gardens surrounding the Baths of Caracalla. The Villa Borghese garden is the best known large green space in Rome, with famous art galleries among its shaded walks. Overlooking Piazza del Popolo and the Spanish Steps are the gardens of Pincio and Villa Medici. There is also a notable pine wood at Castelfusano, near Ostia. Rome also has a number of regional parks of much more recent origin, including the Pineto Regional Park and the Appian Way Regional Park. There are also nature reserves at Marcigliana and at Tenuta di Castelporziano.
Rome today is one of the most important tourist destinations of the world, due to the incalculable immensity of its archaeological and artistic treasures, as well as for the charm of its unique traditions, the beauty of its panoramic views, and the majesty of its magnificent “villas” (parks). Among the most significant resources are the many museums – Musei Capitolini, the Vatican Museums and the Galleria Borghese and others dedicated to modern and contemporary art – aqueducts, fountains, churches, palaces, historical buildings, the monuments and ruins of the Roman Forum, and the Catacombs. Rome is the third most visited city in the EU, after London and Paris, and receives an average of 7–10 million tourists a year, which sometimes doubles on holy years. The Colosseum (4 million tourists) and the Vatican Museums (4.2 million tourists) are the 39th and 37th (respectively) most visited places in the world, according to a recent study.
