The Arch of Constantine is a triumphal arch in Rome dedicated to the emperor Constantine the Great. The arch was commissioned by the Roman Senate to commemorate Constantine’s victory over Maxentius at the Battle of Milvian Bridge in AD 312. Situated between the Colosseum and the Palatine Hill, the arch spans the Via triumphalis, the route taken by victorious military leaders when they entered the city in a triumphal procession. Dedicated in 315, it is the largest Roman triumphal arch, with overall dimensions of 21 m high, 25.9 m wide, and 7.4 m deep. It has three bays, the central one being 11.5 m high and 6.5 m wide and the laterals 7.4 m by 3.4 m each. The arch is constructed of brick-faced concrete revetment in marble. Though dedicated to Constantine, much of the sculptural decoration consists of reliefs and statues removed from earlier triumphal monuments dedicated to Trajan (98–117), Hadrian (117–138), and Marcus Aurelius (161–180).

Civitavecchia is a city and comune of the Metropolitan City of Rome in the central Italian region of Lazio. A seaport on the Tyrrhenian Sea, it is located 60 kilometers (37 miles) west-north-west of the center of Rome. The harbor is formed by two piers and a breakwater, on which stands a lighthouse. Civitavecchia had a population of around 53,000 as of 2015.

The Colosseum or Coliseum, also known as the Flavian Amphitheatre or Colosseo, is an oval amphitheatre in the centre of the city of Rome, Italy. Built of travertine limestone, tuff (volcanic rock), and brick-faced concrete, it was the largest amphitheatre ever built at the time and held 50,000 to 80,000 spectators. The Colosseum is situated just east of the Roman Forum. Construction began under the emperor Vespasian in AD 72 and was completed in AD 80 under his successor and heir, Titus. Further modifications were made during the reign of Domitian (81–96). These three emperors are known as the Flavian dynasty, and the amphitheatre was named in Latin for its association with their family name (Flavius). The Colosseum could hold an estimated 50,000 to 80,000 spectators at various points of its history over the centuries, having an average audience of some 65,000; it was used for gladiatorial contests and public spectacles such as mock sea battles (for only a short time as the hypogeum was soon filled in with mechanisms to support the other activities), animal hunts, executions, re-enactments of famous battles, and dramas based on Classical mythology. The building ceased to be used for entertainment in the early medieval era. It was later reused for such purposes as housing, workshops, quarters for a religious order, a fortress, a quarry, and a Christian shrine. Although substantially ruined because of earthquakes and stone-robbers, the Colosseum is still an iconic symbol of Imperial Rome and is listed as one of the New7Wonders of the World. It is one of Rome's most popular tourist attractions and also has links to the Roman Catholic Church, as each Good Friday the Pope leads a torchlit "Way of the Cross" procession that starts in the area around the Colosseum. In 2018, it was the most popular tourist attraction in the world, with 7.4 million visitors.

The Pantheon, completed in 126AD, was a Roman temple with a surprising oculus that is the building's main source of natural light. The Pantheon of Agrippa, also known as the Roman Pantheon, is one of the architectural masterpieces of the Italian capital. It is the best preserved building from ancient Rome. The construction of the current Pantheon was carried out during the reign of Hadrian, in the year 126 A.D. The name of Agrippa comes from the place in which the current building is built, which was previously occupied by the Pantheon of Agrippa, built in the year 27 B.C and that was destroyed in a fire in the year 80 A.D.

One of Rome's most characteristic Baroque squares, Piazza Navona still has the outline of the Roman stadium built here by Emperor Domitian. It was still used for festivals and horse races during the Middle Ages, and was rebuilt in the Baroque style by Borromini, who also designed the magnificent series of palaces and the church of Sant'Agnese, on its west side. Its facade, campanile, and dome highlight the way Baroque architecture weaves convex and concave surfaces, gables, windows, columns, and piers into a unified design. In the crypt of Sant'Agnese are Alessandro Algardi's 1653 The Miracle of St. Agnes and the remains of a Roman mosaic floor. Sant'Agnese provided a model for Baroque and Rococo churches in Italy and elsewhere.

Roman Forum, Latin Forum Romanum, most important forum in ancient Rome, situated on low ground between the Palatine and Capitoline hills. The Roman Forum was the scene of public meetings, law courts, and gladiatorial combats in republican times and was lined with shops and open-air markets. Under the empire, when it primarily became a center for religious and secular spectacles and ceremonies, it was the site of many of the city’s most imposing temples and monuments.

Rome, Italian Roma, historic city and capital of Roma provincia (province), of Lazio regione (region), and of the country of Italy. Rome is located in the central part of the Italian peninsula, on the Tiber River about 15 miles (24 km) inland from the Tyrrhenian Sea. Once the capital of an ancient republic and empire whose armies and polity defined the Western world in antiquity and left seemingly indelible imprints thereafter, the spiritual and physical seat of the Roman Catholic Church, and the site of major pinnacles of artistic and intellectual achievement, Rome is the Eternal City, remaining today a political capital, a religious center, and a memorial to the creative imagination of the past. Area city, 496 square miles (1,285 square km); province, 2,066 square miles (5,352 square km).

Sistine Chapel, papal chapel in the Vatican Palace that was erected in 1473–81 by the architect Giovanni dei Dolci for Pope Sixtus IV (hence its name). It is famous for its Renaissance frescoes by Michelangelo.

The Spanish Steps are a set of steps in Rome, Italy, climbing a steep slope between the Piazza di Spagna at the base and Piazza Trinità dei Monti, dominated by the Trinità dei Monti church at the top. The monumental stairway of 135 steps (the slightly elevated drainage system is often mistaken for the first step) was built with French diplomat Étienne Gueffier's bequeathed funds of 20,000 scudi, in 1723–1725,[citation needed] linking the Trinità dei Monti church that was under the patronage of the Bourbon kings of France – located above – and the Bourbon Spanish Embassy to the Holy See – located below – in Palazzo Monaldeschi. The stairway was designed by architects Francesco de Sanctis and Alessandro Specchi.

St. Peter’s Basilica, also called New St. Peter’s Basilica, present basilica of St. Peter in Vatican City (an enclave in Rome), begun by Pope Julius II in 1506 and completed in 1615 under Paul V. It is designed as a three-aisled Latin cross with a dome at the crossing, directly above the high altar, which covers the shrine of St. Peter the Apostle. The edifice—the church of the popes—is a major pilgrimage site.

Trevi Fountain is the most beautiful fountain in Rome. Measuring some 20 meters in width by 26 meters in height, Trevi Fountain is also the largest fountain in the city. The origins of the fountain go back to the year 19 B.C., in which period the fountain formed the end of the Aqua Virgo aqueduct. The first fountain was built during the Renaissance, under the direction of Pope Nicholas V. The final appearance of the Trevi Fountain dates from 1762, when after many years of works at the hand of Nicola Salvi, it was finalized by Giuseppe Pannini. Interestingly enough, the name of Trevi derives from Tre Vie (three ways), since the fountain was the meeting point of three streets.

The Vatican City, one of the most sacred places in Christendom, attests to a great history and a formidable spiritual venture. A unique collection of artistic and architectural masterpieces lie within the boundaries of this small state. At its centre is St Peter's Basilica, with its double colonnade and a circular piazza in front and bordered by palaces and gardens. The basilica, erected over the tomb of St Peter the Apostle, is the largest religious building in the world, the fruit of the combined genius of Bramante, Raphael, Michelangelo, Bernini and Maderno.

The Vatican Museums are the public art and sculpture museums in the Vatican City. They display works from the immense collection amassed by the Catholic Church and the papacy throughout the centuries including several of the most renowned Roman sculptures and most important masterpieces of Renaissance art in the world. The museums contain roughly 70,000 works, of which 20,000 are on display, and currently employ 640 people who work in 40 different administrative, scholarly, and restoration departments. Pope Julius II founded the museums in the early 16th century. The Sistine Chapel with its ceiling decorated by Michelangelo and the Stanze di Raffaello decorated by Raphael are on the visitor route through the Vatican Museums. In 2019, they were visited by 6,882,931 persons, which combined made them the third most visited art museum in the world. They are one of the largest museums in the world. There are 54 galleries, or sale, in total,[citation needed] with the Sistine Chapel, notably, being the very last sala within the Museum.
