Top 12 Interesting Facts about Trajan’s Forum

The Roman Forum was the heart of the ancient city of Rome. It was here that most of the important government buildings were located.

Its importance gradually declined over the centuries as the city expanded and even larger structures were constructed, including 5 new Imperial fora.

In this article, you’ll discover some of the most interesting facts about Trajan’s Forum, an incredible ancient landmark in Rome that was completed in the 2nd century A.D.

1. It’s located just a few hundred meters north of the Roman Forum

Trajan’s Forum is one of the 5 Imperial fora that were constructed in ancient Rome between 46 B.C. and 113 A.D. Julius Caesar was the first to build such a public square lined with important buildings and monuments.

Other fora included the Forum of Augustus, the Temple of Peace (also known as the Forum of Vespasian), and the Forum of Nerva.

Trajan’s Forum was both the largest and final of the imperial fora that were constructed during this period in history.

What’s remarkable about these structures is that they are located relatively close to each other in the historical heart of Rome. This particular forum is located just north of the Roman Forum and gradually replaced it as commercial activity and government institutions moved here.

2. It was commissioned by one of the best Roman Emperors

The forum was commissioned by Roman Emperor Trajan (53-117 A.D.), a man who is considered to be one of the best Roman Emperors in history.

This is emphasized by the fact that all new Roman Emperors after him were wished with the words “Felicior Augusto, Melior Traiano” or “May you rule fortunate like Augustus and better than Trajan.”

First Roman Emperor Augustus initiated numerous building programs all across the Roman Empire, and Trajan can hold a candle to his achievements.

Trajan’s Forum was constructed between 106 and 112 A.D. and the spoils of war from the Roman victory against the Dacians were used to build it.

3. Building this monumental forum was an incredible endeavor

The construction project of the forum was led by one of the few ancient architects who we know by name, a man named Apollodorus of Damascus. He was Trajan’s architect and designed numerous structures all across the Empire.

To build the forum in this location, a massive amount of dirt and rock had to be excavated. That’s because the eastern part of the forum was built against Quirinal Hill.

It’s estimated that 300,000 cubic meters (10,594,400 cubic feet) of soil and rock were removed before construction could even start, a massive endeavor considering the workers didn’t have modern-day machinery.

The central part of the forum was a huge open space that was lined with semicircular elements called “exedra” on each side. This plaza was completely covered in Carrara marble and was 300 meters (980 feet) long and 185 meters (07 feet) wide.

4. The Forum is dominated by an ancient shopping mall and a huge column

The eastern section of the forum featured one of the most popular places in ancient Rome, a shopping mall that is known as Trajan’s Market.

This 3-story building has been remarkably well-preserved and is considered to be the first shopping mall in the world. It was constructed on the excavated site of Quirinal Hill.

Other important buildings on the forum were the Basilica Ulpia, a huge civic building, the Temple of Trajan (which was dedicated to the deified Trajan after his death), and two libraries.

RIght in between these libraries, an enormous column was erected called “Trajan’s Column.” This monument stands 38 meters (125 feet) tall and is decorated with reliefs commemorating the Roman victory against the Dacians.

5. A construction project completed in the 1930s partially covered the forum

Nothing of the Carrara marble that once decorated the immense forum remains today. It was quarried from this ancient monuments nd used to build new structures all across the city.

This space was still used as a public square after the Fall of the Western Roman Empire in the 5th century, though, because part of it was strengthened with concrete.

During the Middle Ages, the forum was partially used for farming activities and houses and roads were constructed on top of it. The residential expansion of the city resulted in the forum gradually being buried below the street level and it came to be known as the Alessandrino district.

The Via dei Fori Imperiali was completed in 1933. It connects the forum with the Roman Colosseum and covers parts of the Forum of Trajan, the Forum of Augustus, and the Forum of Nerva. Today, excavations are still being conducted on both sides of this road.
