Trajan's Market

• 1. Introduction

  ›

  Trajan's Market stands today on the Via dei Fori Imperiali in Rome, a complex of ancient ruins that has outlasted empires, convents, and barracks. Walk through its modern entrance at Via Quattro Novembre and you step into a place once alive with free wheat distributions, tavern keepers, and the foot traffic of the Roman capital. The structure is built of brick and concrete, nestled against the excavated flank of the Quirinal Hill, with marble floors still delicate underfoot in places where they have survived nearly two thousand years.

  For a long time, many people called it the world's oldest shopping mall. That label has stuck to Trajan's Market the way barnacles stick to old stone. But scholars today believe the arcaded spaces were more likely administrative offices for Emperor Trajan than commercial stalls in any modern sense. So what exactly was this place? How did it come to be built, who built it, and how did a Roman imperial complex transform over centuries into the layered, multi-level ruin we can walk through now?

• 2. Apollodorus and the Build

  ›

  Apollodorus of Damascus was not a designer who worked at a comfortable distance from his patron. He followed Trajan through his military adventures and became the architect Trajan trusted above all others to plan his Forum. The market complex was probably built between 100 and 110 AD, an undertaking that required cutting into the Quirinal Hill itself to create the terraced, multi-level structure visitors still climb through today.

  The inauguration came in 113 AD, making the complex a companion to Trajan's Forum from its earliest public years. The engineering choices Apollodorus made were durable ones. The grand hall is roofed by a concrete vault raised on piers, a design that both covers the central space and allows air and light to filter in. Brick and concrete dominate throughout, materials that proved better suited to the centuries ahead than many of the marble surfaces they once supported.

• 3. Life Inside the Market

  ›

  A shop unit inside the market carried a specific name: taberna. The spaces were arranged on two different sides of a shopping area, and free wheat was distributed to the people of Rome within what is now the entry hall. That detail alone shifts how a visitor reads the space. This was not simply a place of commerce; it was woven into the city's system of public provision.

  Cutting through the complex is the Via Biberatica, a road whose name comes from the Latin bibo and bibere, meaning "to drink." The street earned that name because it was lined with Roman taverns and grocers' shops. A large balcony at the end of the main hall looks out over the markets, Trajan's Forum, and the Vittoriano. Lower in the complex, two large halls survive that were probably used for auditions or concerts. A giant exedra formed by the market structure was originally mirrored by a matching exedral boundary space on the south flank of Trajan's Forum, giving the whole ensemble a geometric symmetry that is easier to grasp now from above than it would have been at street level in antiquity.

• 4. Centuries of Transformation

  ›

  During the Middle Ages, the complex did not sit empty or untouched. New floor levels were added, and those additions are still visible today, layered into the ancient fabric. Defensive elements went up alongside them, including the Torre delle Milizie, the so-called "militia tower," which was built in 1300 and still rises above the site.

  In the sixteenth century a convent was built in the area. The Italian state acquired that convent in 1885, and it was converted into the Goffredo Mameli barracks. At the beginning of the twentieth century, those barracks were demolished. The demolition was carried out specifically to restore Trajan's Markets to something closer to their ancient form, clearing away the military occupation that had most recently occupied the site.

• 5. The Museum That Opens It Up

  ›

  The Museum of the Imperial Fora, known in Italian as the Museo dei Fori Imperiali, opened in 2007. It sits within the market complex and holds artifacts gathered from all of ancient Rome's forums, not from Trajan's Forum alone. That breadth gives the museum an unusual scope; a visitor moving through its rooms is moving through evidence from across the whole landscape of imperial Roman public space.

  The modern entrances to Trajan's Market are at two addresses: Via Quattro Novembre 94 and Piazza Madonna di Loreto. Among the surviving details that reward a close look are delicate marble floors and the remains of a library, evidence that the complex served intellectual as well as administrative and commercial purposes in its heyday.
