The Pyramid of Cestius is an ancient pyramid in Rome, Italy, near the Porta San Paolo and the Protestant Cemetery. Due to its incorporation into the city's fortifications, it is today one of the best-preserved ancient buildings in Rome. The pyramid was built about 18 BC–12 BC as a tomb for Gaius Cestius Epulo, a magistrate and member of one of the four great religious corporations at Rome, the Septemviri Epulonum. It is of brick-faced concrete covered with slabs of white marble standing on a travertine foundation, measuring 100 Roman feet (29.6 m) square at the base and standing 125 Roman feet (37 m) high.

The Circus Maximus is an ancient Roman chariot racing stadium and mass entertainment venue located in Rome. Situated in the valley between the Aventine and Palatine hills, it was the first and largest Chariot Racing Stadium in ancient Rome. The site is now a public park and retains little evidence of its former use. The Circus could hold over 1/4 of the city's population, over 250,000 people, allowing for this Circus to be a popular viewing place by the Romans. The first version, later rebuilt, was made completely from wood. It is believed that first Ludi Romani (Roman Games) were staged at the location by Tarquinius Priscus, the fifth king of Rome.

The Arch of Constantine is a triumphal arch in Rome, situated between the Colosseum and the Palatine Hill. It was erected to commemorate Constantine I's victory over Maxentius at the Battle of Milvian Bridge on October 28, 312. Dedicated in 315, it is the latest of the existing triumphal arches in Rome, from which it differs by spolia, the extensive re-use of parts of earlier buildings. The arch is heavily decorated with parts of older monuments, which assume a new meaning in the context of the Constantinian building. As it celebrates the victory of Constantine, the new "historic" friezes illustrating his campaign in Italy convey the central meaning: the praise of the emperor, both in battle and in his civilian duties.

The Palatine Hill is the centermost of the Seven Hills of Rome and is one of the most ancient parts of the city. It stands 40 metres above the Forum Romanum, looking down upon it on one side, and upon the Circus Maximus on the other. According to Roman mythology, the Palatine Hill was the location of the cave, known as the Lupercal, where Romulus and Remus were found by the she-wolf that kept them alive. Rome has its origins on the Palatine. Indeed, recent excavations show that people have lived there since approximately 1000 BC. Many affluent Romans of the Republican period (510 BC – c. 44 BC) had their residences there.

The Colosseum or Roman Coliseum, originally the Flavian Amphitheatre, is an elliptical amphitheatre in the center of the city of Rome, Italy, the largest ever built in the Roman Empire. It is considered one of the greatest works of Roman architecture and Roman engineering. Occupying a site just east of the Roman Forum, its construction started between 70 and 72 AD under the emperor Vespasian and was completed in 80 AD under Titus, with further modifications being made during Domitian's reign (81–96). As well as the gladiatorial games, other public spectacles were held there, such as mock sea battles, 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.

The Imperial Fora consist of a series of monumental fora (public squares), constructed in Rome over a period of one and half centuries, between 46 BC and 113 AD. The forums were the center of the Roman Republic and of the Roman Empire. Julius Caesar decided to construct a large forum bearing his name. In the battle of Philippi in 42 BC Augustus vowed to build a temple dedicated to Mars Ultor (Mars the Avenger). The incomplete forum was inaugurated, after 40 years of construction, in 2 BC, adding the second monumental square, the Forum of Augustus. The Forum square was closed by the Basilica Ulpia, with Trajan's Column at its back.

The Column of Marcus Aurelius, is a Doric column, with a spiral relief, built in honour of Roman emperor Marcus Aurelius and modeled on Trajan's Column. It still stands on its original site in Rome, in Piazza Colonna before Palazzo Chigi. Because the original dedicatory inscription has been destroyed, it is not known whether it was built during the emperor’s lifetime or after his death in 180; however, an inscription found in the vicinity attests that the column was completed by 193. The spiral picture relief tells the story of Marcus Aurelius’ Danubian or Marcomannic wars, waged by him from 166 to his death.

The Pantheon. meaning "Every god", is a building in Rome, commissioned by Marcus Agrippa as a temple to all the gods of Ancient Rome, and rebuilt by Emperor Hadrian in about 126 AD. The building is circular with a portico of three ranks of huge granite Corinthian columns under a pediment opening into the rotunda, under a coffered, concrete dome, with a central opening (oculus) to the sky. Almost two thousand years after it was built, the Pantheon's dome is still the world's largest unreinforced concrete dome. It is one of the best preserved of all Roman buildings.

Piazza Navona is a city square in Rome, Italy. It is built on the site of the Stadium of Domitian, built in first century AD, and follows the form of the open space of the stadium. Defined as a public space in the last years of 15th century, when the city market was transferred to it from the Campidoglio, the Piazza Navona is a significant example of Baroque Roman architecture and art. During its history, the piazza has hosted theatrical events and other ephemeral activities.

The Theatre of Marcellus is an ancient open-air theatre built in the closing years of the Roman Republic. At the theatre, locals and visitors alike were able to watch performances of drama and song. Today its ancient edifice in the rione of Sant'Angelo, Rome, once again provides one of the city's many popular spectacles or tourist sites. It was named after Marcus Marcellus, Emperor Augustus's nephew, who died five years before its completion. Space for the theatre was cleared by Julius Caesar, who was murdered before it could be begun; the theatre was so far advanced by 17 BC that part of the celebration of the ludi saeculares took place within the theatre; it was completed in 13 BC and formally inaugurated in 12 BC by Augustus.
