Giacomo Boni and the Transformation of the Roman Forum

Giacomo Boni (1859–1925) was not Roman by birth but Venetian, and that background shaped the way he approached the ancient city. Born in Venice, a place defined by layers of history, adaptation, and reuse, Boni arrived in Rome at a pivotal moment. Following Italian unification in 1870, the new capital became both a construction site and a symbol of national identity. Archaeology played an important role in that process, helping to connect modern Italy to the legacy of ancient Rome.

Unlike many scholars of his time, Boni did not come from a strictly academic background. Trained in architecture and restoration, he developed a deep interest in material culture and archaeological method. This perspective led him to view Rome not simply as a collection of monuments but as a landscape shaped by centuries of continuous occupation. Influenced by emerging archaeological practices in Europe, he became one of Italy’s earliest and most influential advocates of stratigraphic excavation, the study of historical layers and their relationships to one another.

When Boni was appointed director of excavations in the Roman Forum in 1898, he transformed the site into one of Italy’s most important archaeological projects. His work extended across the Forum, the Comitium, and parts of the Palatine Hill. Among his most significant and controversial decisions was the demolition of the medieval church of Santa Maria Liberatrice. The removal of the church revealed the much older church of Santa Maria Antiqua and preserved one of the most important collections of early Christian wall paintings in Rome. Recognizing the need for protection, Boni installed a roof over the site, an innovative conservation measure for its time.

Boni’s excavations also uncovered the Lacus Iuturnae, helping scholars better understand the sacred and hydraulic systems of the Forum. He reshaped interpretations of the Temple of Vesta and carried out a partial reconstruction using architectural fragments to suggest the monument’s ancient appearance. Although later generations have debated the balance between reconstruction and authenticity, his work established the image of the temple familiar to many visitors today. Nearby, he reorganized and re-excavated the House of the Vestals, emphasizing the site’s original layout and function.

Boni was also an innovator in archaeological documentation. He experimented with aerial photography using balloons and sought new ways to understand Rome’s urban landscape from above. This approach anticipated techniques that would later become standard in archaeological research. At the same time, his vision of the Forum was selective. Medieval walls, industrial remains, and other later additions were often removed to highlight the ancient city. The result was a Forum that was easier to understand as a classical monument but less representative of its full historical development.

His influence extended beyond the Forum itself. Boni worked in the area of the Basilica of Maxentius and carried out important interventions on the Palatine Hill, including the reconstruction of portions of Domitian’s ramp. These projects helped shape the appearance of the archaeological park that visitors encounter today.

Boni’s legacy remains complex. He introduced scientific excavation methods, championed stratigraphy, and made some of the most important discoveries in the history of Roman archaeology. At the same time, he helped create a particular vision of ancient Rome centered on its classical and imperial past. Modern debates about excavation, restoration, and preservation continue to engage with the choices he made and the landscape he left behind.
