Trajan's Forum, Rome. Church Santa Maria di Loreto, Trajan's column and church Chiesa Santissimo Nome di Maria.

Trajan's Forum (Latin: Forum Traiani) was the last of the Imperial fora to be constructed in ancient Rome. The famous architect Apollodorus of Damascus oversaw its construction.
This forum was built on the order of the emperor Trajan with the spoils of war from the conquest of Dacia, which ended in 106. The Fasti Ostienses state that the Forum was inaugurated in 112, while Trajan's Column was erected and then inaugurated in 113. In modern times only a section of the markets and the column of Trajan remain. A number of columns which historically formed the Basilica Ulpia remained on site, and have been re-erected.
Trajan's Column (Italian: Colonna Traiana, Latin: COLVMNA·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, built near the Quirinal Hill, north of the Roman Forum. Completed in AD 113, the freestanding column is most famous for its spiral bas relief, which artistically describes the epic wars between the Romans and Dacians. Its design has inspired numerous victory columns, both ancient and modern.

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.

Santa Maria di Loreto is a 16th-century church in Rome, central Italy, located just across the street from the Trajan's Column, near the giant National Monument. After the Jubilee of 1500, the association of metallurgical (Sodalizio dei Fornai) received permission from Pope Alexander VI to build a church at this site. Construction of this church began in 1507 by Antonio da Sangallo the younger, with an octagonal floor plan; the dome and the lantern were completed by Jacopo del Duca some 75 years later. The church was built atop an earlier 15th century chapel, which contained an icon of the Virgin of Loreto, hence the church retained the icon and acquired the title. It is most notable for the adjacent erection of a similarly domed, but pale marble, 18th-century church Santissimo Nome di Maria al Foro Traiano, giving the semblance of twin churches.
