Apollodorus of Damascus in the context of "Trajan's Forum"

Trajan's Dacian Wars (101–102, 105–106) were two military campaigns fought between the Roman Empire and the Dacians under King Decebalus during the reign of Emperor Trajan. The conflicts stemmed from repeated Dacian incursions into the province of Moesia and from Rome's growing need for resources. Discontent with the treaty Domitian had concluded with Decebalus in 89 CE persisted, and Trajan, keen to assert himself as a soldier-emperor, took the opportunity to reassert Roman authority.

Trajan's First Dacian War began in 101 CE, when the emperor led a major offensive across the Danube using a pontoon bridge constructed by his engineer Apollodorus of Damascus, who also cut a road through the river cliffs. The Romans won a series of victories, including at Tapae and Adamclisi. Before Trajan could capture the Dacian capital, Sarmizegetusa, Decebalus sought peace. The treaty forced him to surrender territory and engineers provided by Domitian, return equipment, accept Roman garrisons, and refrain from crossing the Danube.

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.

A taberna (pl.: tabernae) was a type of shop or stall in Ancient Rome. Originally meaning a single-room shop for the sale of goods and services, tabernae were often incorporated into domestic dwellings on the ground level flanking the fauces, the main entrance to a home, but with one side open to the street. As the Roman Empire became more prosperous, tabernae were established within great indoor markets and were often covered by a barrel vault. Each taberna within a market had a window above it to let light into a wooden attic for storage and had a wide doorway. A famous example of such an indoor market is the Markets of Trajan in Rome, built in the early 2nd century by Apollodorus of Damascus.

According to the Cambridge Ancient History, a taberna was a "retail unit" within the Roman Empire and was where many economic activities and many service industries were provided, including the sale of cooked food, wine, and bread.

Trajan's Bridge (Romanian: Podul lui Traian; Serbian: Трајанов мост, romanized: Trajanov most), also called Bridge of Apollodorus over the Danube, was a Roman segmental arch bridge, on the modern Serbian - Romanian border, the first bridge to be built over the lower Danube and considered one of the greatest achievements in Roman architecture. Though it was functional for only 165 years, it is often considered to have been the longest arch bridge in both total span and length for more than 1,000 years.

The bridge was completed in 105 AD and designed by Emperor Trajan's architect Apollodorus of Damascus before the Second Dacian War to allow Roman troops to cross the river. Fragmentary ruins of the bridge's piers are still in existence.

The Thomas Jefferson Memorial is a national memorial in Washington, D.C., built in honor of Thomas Jefferson, the principal author of the United States Declaration of Independence and the nation's third president. Built between 1939 and 1943, the memorial features multiple quotes from Jefferson intended to capture his ideology and philosophy, known as Jeffersonian democracy. Jefferson was widely considered among the most influential political minds of his era and one of the most consequential intellectual forces behind both the American Revolution and the American Enlightenment.

The Jefferson Memorial is built in neoclassical style and is situated in West Potomac Park on the shore of the Potomac River. It was designed by John Russell Pope, a New York City architect, and built by Philadelphia contractor John McShain. Construction on the memorial began in 1939 and was completed in 1943, though the bronze statue of Jefferson was not completed and added until four years after its dedication and opening, in 1947. Pope made references to the Roman Pantheon, whose designer was Apollodorus of Damascus, and to Jefferson's own design for the rotunda at the University of Virginia as inspirations for the memorial's aesthetics. The Jefferson Memorial and the White House form anchor points to the National Mall in Washington, D.C..
