Colosseum’s Southern Piazza Restored After Four Years, Reframing Rome’s Ancient Landmark
A newly completed restoration has changed the way visitors approach the Roman Colosseum. After four years of construction, the amphitheater’s southern piazza has been returned to view, with Stefano Boeri Interiors leading the project that recreated the travertine-paved pedestrian space outside the monument’s southern façade.
The intervention is deliberately restrained. Rather than rebuilding the lost two-story arcade that once rose along this side of the Colosseum, the design team marked the original column positions with plinths made from the same stone used in the piazza. The result is less a reconstruction than a spatial correction: a way of restoring the monument’s footprint and making its scale legible again.
Built between 70 and 80 CE, the Colosseum remains one of the most ambitious structures of the ancient world. It rose four stories high, contained 80 arched entrances, and could seat 50,000 or more people. Its engineering was equally remarkable. The amphitheater stood freestanding, supported by a complex vault system, and included a retractable awning to shade spectators, along with latrines and water fountains. It was also a site of violence and spectacle, hosting gladiator games, public executions, and mock naval battles.
The building’s later history is as layered as its original function. After the fall of the Roman Empire, it was used as a Christian sanctuary and later as a fortress. An earthquake in 1349 left it partially destroyed, and the structure was then quarried for materials used in projects such as St. Peter’s Basilica and the Palazzo Venezia. In the 1800s, Pope Pius VIII led preservation efforts that helped define the monument’s modern condition.
Stefano Boeri said in a statement that the project has “finally restored the perception of the monument’s original size and floor level.” He added that it allows the public to approach the walls and imagine the rhythm of the ambulatories and arches that once organized the building’s southern edge.
For a monument so often encountered as an image, the restored piazza offers something more precise: a renewed sense of how the Colosseum was meant to be entered, read, and inhabited.
