Rome
Rome is the capital city of Italy. It is very, very old. You can still see buildings from long ago, like a giant round arena.
Rome, the capital of Italy, grew from huts on a hill beside the Tiber River into the center of a huge ancient empire. About 2.7 million people live there today (2023), among ruins such as the Colosseum and the Pantheon.
Rome grew from Iron Age huts on the Palatine Hill into the capital of the Roman Republic and Empire, then the city of the popes, and since 1870 the capital of Italy. Its historic center is a World Heritage Site, and about 2.75 million people lived in the city in 2023.

Rome is the capital city of Italy.
It is built beside a river called the Tiber. Rome is very old. People still walk past buildings that are nearly 2,000 years old!
Rome is the capital of Italy, in the middle of the long Italian peninsula. It stands on the Tiber River, about 24 kilometers inland from the Tyrrhenian Sea. About 2.7 million people lived in the city in 2023.
More than 2,000 years ago, Rome was the center of an empire that stretched across Europe, North Africa and western Asia. Its roads, laws, arches and the Latin language spread far and wide. Today ancient ruins, grand churches and busy modern streets all crowd together. No wonder Britannica calls Rome the Eternal City.
Rome, capital of Italy and of the Lazio region, lies in the central Italian peninsula on the Tiber, about 24 km inland from the Tyrrhenian Sea. The city covers 1,285 km² and had a population of 2,748,109 in 2023. Britannica describes it as a political capital, a religious center and "a memorial to the creative imagination of the past".
As the heart of the Roman Republic and Empire, Rome spread Latin, Roman law, arches, concrete building, roads and aqueducts across Europe and North Africa; its idea of a republic with assemblies and a senate shaped later representative governments. Vatican City, the seat of the Roman Catholic Church and the world's smallest fully independent state, is an enclave surrounded by Rome on the west bank of the Tiber.

Famous places
Rome has many very old buildings.
The Colosseum is a giant round arena. The Pantheon has a huge round roof called a dome. The Trevi Fountain splashes water into a big pool. People toss coins into it.
The Colosseum, built about 70 to 80 CE, is a huge oval arena with seats all around for up to 50,000 people, who came to watch shows. Nearby lies the Roman Forum, once the busy center of the ancient city. The Pantheon, rebuilt by the emperor Hadrian between 118 and 128 CE, is a round building with a dome made of concrete.
Much younger is the Trevi Fountain, designed by Nicola Salvi in the 1700s. Its water still comes from an ancient aqueduct, and many visitors toss coins into it. Across the Tiber, in Vatican City, stands St. Peter's Basilica.
UNESCO inscribed the Historic Centre of Rome in 1980 and extended it in 1990 to the 17th-century walls of Urban VIII. It covers major monuments of antiquity, including the Forums, the Mausoleum of Augustus, the Mausoleum of Hadrian (now Castel Sant'Angelo), the Pantheon and the Columns of Trajan and Marcus Aurelius, and the religious and public buildings of papal Rome.
The Colosseum, the largest amphitheater of the Roman Empire, was begun under the emperor Vespasian in 70 to 72 CE and dedicated by his son Titus in 80 CE; it could hold as many as 50,000 spectators. The Pantheon was first a classical temple; Hadrian rebuilt it in 118 to 128 CE as a circular building with a concrete dome. The Aurelian Wall, begun in 270 CE in brick-faced concrete, runs about 20 km and is still largely intact. The Trevi Fountain, designed by Nicola Salvi in the 18th century, is fed by the ancient Acqua Vergine aqueduct, whose water was long thought Rome's softest and best tasting.

From hilltop huts to a world capital
Long ago, people built small huts on a hill by the river.
The village grew into a big city. Its leaders ruled lands far away. Later, many old buildings fell apart. Then Rome grew again and became Italy's capital.
Archaeologists have found the remains of huts from the 700s and 600s BCE on the Palatine Hill, one of the hills the city grew around. Rome became a republic, then the center of an empire. By the late first and early second centuries CE it was at its grandest; some estimates put its population at more than a million, though it was probably less.
Later, Rome was attacked and robbed several times, and many old buildings fell into ruin, but it remained the city of the popes. In 1870 Italian troops entered Rome, and it became the capital of a united Italy. In 1946 Italy became a republic, and in 1960 Rome hosted the Olympic Games.
Rome began on the Palatine, a defensible hill above the last high-banked crossing of the Tiber, where an island eased the way across. Excavations there have revealed Iron Age huts of the 8th–7th century BCE. The city grew around a group of hills traditionally counted as seven. After the Gauls sacked it in 390 BCE, the Servian Wall was built; Rome led a republic and then an empire that embraced England, continental Europe, northern Africa and most of Asia west of the Euphrates. Augustus reorganized its government and created a fire brigade, and in the late 1st and early 2nd centuries CE its population has been estimated at more than a million, though probably less.
Rome was sacked by the Visigoths in 410 and the Vandals in 455, and stripping ancient buildings for materials from the 9th to the 16th century destroyed more of the classical city than any other force. As the seat of the popes it recovered its wealth and became a capital of the arts. Italian troops entered on September 20, 1870, and after a plebiscite Rome became Italy's capital; in 1929 Italy and Vatican City recognized each other's sovereignty. German forces occupied the city during World War II, and in 1946 a referendum declared Italy a republic.
Getting around Rome
Long ago, the Romans built long, straight roads.
Some of those old roads still lead into Rome! Today people ride buses, trams and trains under the ground. The streets are often full of cars.
The ancient Romans built great roads that led to their capital, such as the Via Appia, or Appian Way. Some are still used, and a ring road about 10 kilometers from the center links them together. Rome's main street, the Via del Corso, follows the line of another ancient road.
Digging a subway was hard in a city full of buried ruins. The first line, from the main station, Stazione Termini, was running by 1955, and more lines and tram routes have been added since. Even so, traffic jams are a big problem. Two airports serve Rome: Fiumicino on the coast and the smaller Ciampino.
The antique viae, among them the Via Appia, Via Aurelia and Via Flaminia, still radiate from the city; a belt highway about 10 km out ties them together. The Via del Corso, the main street of central Rome, was the Via Flaminia in classical times.
Subway building was long held back by the monuments themselves. Mussolini decreed a line from the Stazione Termini, which was operating along a southwestern route by 1955; a comprehensive metropolitan system was approved in 1959, and in the 1990s Mayor Francesco Rutelli extended the subway and built tramlines. Britannica notes that traffic fumes and vibration speed the decay of monuments and that traffic and parking remain central problems. Leonardo da Vinci (Fiumicino) Airport lies on the coast about 24 km southwest of the city, and the smaller Ciampino Airport about 11 km southeast.

Sun, rain and winds
Summers in Rome are hot and dry.
In the afternoon, a cool breeze often blows in from the sea. Winters are mild. Once in a while, a little snow falls.
Rome's summers are hot and dry, with afternoon temperatures often above 24 °C. On many summer afternoons a west wind called the ponentino blows in from the Tyrrhenian Sea and cools the city down.
Winters are mild, with daytime highs of about 10 °C, though there are some frosts and, now and then, a light snowfall. In winter a cold, dry wind from the north, the tramontana, often blows. About 750 millimeters of rain falls in a year, most of it in spring and autumn.
Rome has hot, dry summers, with highs often above 24 °C, frequently relieved in the afternoon by the ponentino, a west wind off the Tyrrhenian Sea. Annual precipitation is roughly 750 mm, with spring and autumn the rainiest seasons. Winters are mild, with average highs just above 10 °C, broken by frosts and occasional light snow; the tramontana, a cold, dry north wind, is common then.
The city's setting also shapes its past and future. The Roman countryside, the Campagna, was one of the last parts of central Italy to be settled in antiquity. Today Britannica warns that a labyrinth of old tunnels and underground chambers undermines parts of the city, and that traffic fumes and vibration add to the wear on its monuments.

Living in Rome
Rome has lots of fountains and old squares.
Many families live in big apartment buildings outside the old center. Many people work for Italy's government. Others help the visitors who come to see Rome.
Rome's population has risen and fallen over the centuries. In 1870 only about 226,000 people lived there. By 1930 there were more than a million, and by 1967 more than 2.6 million. Masses of modern apartment buildings now rise in the districts outside the old center.
The old center itself is packed with history: more than 200 palaces, several big parks and the houses of Italy's parliament, along with hundreds of hotels and thousands of offices, restaurants and cafés. Rome is not mainly a factory city; tens of millions of Italians and visitors from abroad come each year for its culture, shops and entertainment.
After unification in 1870, when the city had only about 226,000 inhabitants and wide open spaces inside its walls, Rome passed 500,000 before World War I and 1,000,000 by 1930; it grew from just over 1,960,000 in 1951 to more than 2,610,000 in 1967. The ancient center is divided into 22 rioni, most named since classical times, surrounded by 35 quartieri urbani absorbed after 1911 and six large suburbi.
Inside the old walls are more than 200 palazzi, several major parks, the residence of the Italian president, the houses of parliament and government offices. Rome is not mainly an industrial city but a political capital and a cultural, shopping and entertainment center that draws tens of millions of visitors a year; the Church, with its communications and souvenir businesses and thousands of workers, plays a significant part in the economy. Federico Fellini made most of his films here, including La dolce vita (1960).

Italy is shaped a bit like a boot. Rome is near the middle of the boot. A tiny country, Vatican City, is inside Rome!
Rome is in central Italy, on the Tiber River, about 24 kilometers from the Tyrrhenian Sea. The ancient city grew around a group of hills, traditionally counted as seven, with the Palatine Hill beside the river crossing.
Inside Rome, on the west bank of the Tiber, is Vatican City, the smallest fully independent country in the world. It is completely surrounded by Rome.
Rome lies at about 41.9° N and 12.5° E, in central Italy, on the Tiber about 24 km inland from the Tyrrhenian Sea. Its first site, the Palatine, overlooked the last downstream, high-banked crossing of the Tiber, eased by an island in midstream. The hills traditionally counted as seven are the Palatine, Capitoline, Quirinal, Viminal, Esquiline, Caelian and Aventine.
The Aurelian Wall, about 20 km around and enclosing about 10 km², still circles much of the historic center. Vatican City, Britannica's "world's smallest fully independent nation-state", is an enclave surrounded by Rome on the west bank of the Tiber; Italy and the Vatican recognized each other's sovereignty in 1929.
