Temple of Trajan

Trajan's Forum (Latin: Forum Traiani; Italian: Foro di Traiano) was the last of the Imperial fora to be constructed in ancient Rome. The architect Apollodorus of Damascus oversaw its construction.

Trajan's Market (Latin: Mercatus Traiani; Italian: Mercati di Traiano) is a large complex of ruins in the city of Rome, Italy, located on the Via dei Fori Imperiali, at the opposite end to the Colosseum. The surviving buildings and structures, built as an integral part of Trajan's Forum and nestled against the excavated flank of the Quirinal Hill, present a living model of life in the Roman capital and a glimpse at the restoration in the city, which reveals new treasures and insights about ancient Roman architecture.Thought to be the world's oldest shopping mall, the arcades in Trajan's Market are now believed by many to be administrative offices for Emperor Trajan. The shops and apartments were built in a multi-level structure and it is still possible to visit several of the levels. Highlights include delicate marble floors and the remains of a library.

The Casa dei Cavalieri di Rodi (House of the Knights of Rhodes) is a building in Rome. Sited in the ruins of the Forum of Augustus, it was built by the Knights Hospitaller at the end of the 13th century and since 1946 has been used by their successors, the Sovereign Military Order of Malta.

The Cloaca Maxima (Latin: Cloāca Maxima, lit. Greatest Sewer) was one of the world's earliest sewage systems. Its name derives from Cloacina, a Roman goddess. Built during either the Roman Kingdom or early Roman Republic, it was constructed in Ancient Rome in order to drain local marshes and remove waste from the city. It carried effluent to the River Tiber, which ran beside the city. The sewer started at the Forum Augustum and ended at the Ponte Rotto and Ponte Palatino. It began as an open air canal, but it developed into a much larger sewer over the course of time. Agrippa renovated and reconstructed much of the sewer. This would not be the only development in the sewers. By the first century CE all eleven Roman aqueducts were connected to the sewer. After the Roman Empire fell the sewer still was used. By the 1800s it became a tourist attraction. Some parts of the sewer are still used today. Whilst still being used it was highly valued as a sacred symbol of Roman culture, and Roman engineering.

San Giovanni Battista dei Cavalieri di Rodi (Saint John the Baptist of the Knights of Rhodes) is a church in Rome, on piazza del Grillo in the Monti district. Its full title is the Palatine Chapel of Saint John the Baptist of the Knights of Rhodes (cappella palatina di San Giovanni Battista dei Cavalieri di Rodi).

Santa Caterina a Magnanapoli is a baroque church dedicated to St. Catherine of Siena on Largo Magnanapoli on the slopes of the Quirinal Hill in Rome.

The Imperial fora (Fori Imperiali in Italian) are a series of monumental fora (public squares), constructed in Rome over a period of one and a half centuries, between 46 BC and 113 AD. The fora were the center of the Roman Republic and of the Roman Empire. The Imperial fora, while not part of the Roman Forum, are located relatively close to each other. Julius Caesar was the first to build in this section of Rome and rearranged both the Forum and the Comitium, another forum type space designated for politics, to do so. These fora were the centres of politics, religion and economy in the ancient Roman Empire. During the early 20th century, Mussolini restored the Imperial Fora as part of his campaign to evoke and emulate the past glories of Ancient Rome. But he also built the Via dei Fori Imperiali across the middle of the site. The modern street and its heavy traffic has proved a source of damage to the buildings because of vibration and pollution. There have been a number of proposals to remove the road, but none have taken effect.

The Basilica Ulpia was an ancient Roman civic building located in the Forum of Trajan. The Basilica Ulpia separates the temple from the main courtyard in the Forum of Trajan with the Trajan's Column to the northwest. It was named after Roman emperor Trajan whose full name was Marcus Ulpius Traianus.It became perhaps the most important basilica after two ancient ones, the Basilicas Aemilia and Julia. With its construction, much of the political life moved from the Roman Forum to the Forum of Trajan. It remained so until the construction of the Basilica of Maxentius and Constantine. Unlike later Christian basilicas, it had no known religious function; it was dedicated to the administration of justice, commerce and the presence of the emperor. It was the largest in Rome measuring 117 by 55 meters (385 x 182 ft).

The Church of the Most Holy Name of Mary at the Trajan Forum (Italian: Santissimo Nome di Maria al Foro Traiano, Latin: Ss. Nominis Mariae ad forum Traiani) is a Roman Catholic church in Rome, Italy. This church should not be confused with the church Santissimo Nome di Maria in Via Latina in south-east Rome. The pale marble church stands in front of the Column of Trajan, a few dozen steps from the similarly domed, but externally more colorful, church of Santa Maria di Loreto. The feast of the Holy Name of Mary was instituted by Pope Innocent XI after the victory of the Austrian-Polish armies under the command of John III Sobieski over the Turks at the Battle of Vienna in 1683. Abbot Giuseppe Bianchi instituted devotion to the most holy name of Mary in 1685 at Santo Stefano del Cacco, and soon afterwards established the Congregation of the Most Holy Name of Mary, which was formally approved in 1688.

The Bibliotheca Ulpia ("Ulpian Library") was a Roman library founded by the Emperor Trajan in AD 114 in his forum, the Forum of Trajan, located in ancient Rome. It was considered one of the most prominent and famous libraries of antiquity and became the major library in the Western World upon the destruction of the Library of Alexandria in the 3rd century. It was the only Roman library to survive until the Fall of Rome in the mid-fifth century.

Trajan's Column (Italian: Colonna Traiana, Latin: Columna Traiani) is a Roman triumphal column in Rome, Italy, that commemorates Roman emperor Trajan's victory in the Dacian Wars. It was probably constructed under the supervision of the architect Apollodorus of Damascus at the order of the Roman Senate. It is located in Trajan's Forum, north of the Roman Forum. Completed in AD 113, the freestanding column is most famous for its spiral bas relief, which depicts the wars between the Romans and Dacians (101–102 and 105–106). Its design has inspired numerous victory columns, both ancient and modern. The structure is about 30 metres (98 feet) in height, 35 metres (115 feet) including its large pedestal. The shaft is made from a series of 20 colossal Carrara marble drums, each weighing about 32 tons, with a diameter of 3.7 metres (12.1 feet). The 190-metre (620-foot) frieze winds around the shaft 23 times. Inside the shaft, a spiral staircase of 185 steps provides access to a viewing deck at the top. The capital block of Trajan's Column weighs 53.3 tons, and had to be lifted to a height of about 34 metres (112 feet).Ancient coins indicate preliminary plans to top the column with a statue of a bird, probably an eagle. After construction, a statue of Trajan was put in place; this disappeared in the Middle Ages. On December 4, 1587, the top was crowned with a bronze figure of Saint Peter the Apostle by Pope Sixtus V, which remains to this day.Trajan's Column was originally flanked by two sections of the Ulpian Library, a Greek chamber and a Latin chamber, which faced each other and had walls lined with niches and wooden bookcases for scrolls. The Latin chamber likely contained Trajan's commentary on the Roman-Dacian Wars, the Dacica, which most scholars agree was intended to be echoed in the spiralling, sculpted narrative design of Trajan's Column.

The Forum of Augustus (Latin: Forum Augustum; Italian: Foro di Augusto) is one of the Imperial fora of Rome, Italy, built by Augustus. It includes the Temple of Mars Ultor. The incomplete forum and its temple were inaugurated in 2 BC, 40 years after they were first vowed.
