AI and Ultra-High-Definition Tech Restore Italy's Basilica of Saint Francis
Four people were killed by falling rubble during the 1997 earthquakes that damaged the basilica.
The technology is not the purpose. It's a tool to reach the goal.
Mark
So the basilica was damaged in 1997, and they're only now getting serious about restoration?
Mimi
Not quite. Restorers like Sergio Fusetti have been working continuously since the quakes. But after thirty years of manual labor, they've hit a wall. There are eighty thousand fragments still in storage with no clear home. That's where the technology comes in.
Luke
Wait—eighty thousand fragments, and they don't know where they go? How many pieces are we talking about that actually got reassembled in those thirty years?
Mimi
The reporting doesn't give us that number. Fusetti mentions sometimes placing just one piece in a full day of work, which suggests the pace was slow, but we don't have a total count of what's been restored versus what's still waiting.
Mark
And the AI is supposed to solve that?
Mimi
That's the theory. Borelli says AI can analyze cracks, discoloration, and lifting paint in minutes instead of years. The implication is that it could also help match fragments to their original locations, but the reporting doesn't spell out exactly how that works.
Luke
Right. The technology sounds remarkable, but we're taking Borelli's word that it can actually solve the fragment problem. The article shows us the cameras and the VR experiences, but it doesn't show us AI actually reassembling pieces of the basilica.
Mark
Is that a problem?
Luke
It's a gap. The story is about restoration, but the restoration part is still theoretical. What we see working is the documentation—the gigapixel photography, the 3D mapping. That's real and complete. The AI application to the actual restoration is still in the planning stage.
Mimi
Fair point. But the friars clearly believe in it enough to partner with the company. And having a perfect digital record of the basilica is valuable in itself, even if the fragment reassembly takes longer than Borelli hopes.
Mark
What about the broader vision—the VR experiences in Pompeii and the paintings?
Mimi
That's separate from the basilica restoration, but it shows what Borelli's company is capable of. They're using the same technology to make cultural heritage accessible in new ways.
Luke
And that's working. The article shows Whitaker actually experiencing it. But again, there's a difference between documenting a space in ultra-high-definition and creating an emotionally resonant VR experience. Borelli admits the technology can't yet duplicate the emotional impact of standing in front of an original work. That's an honest limitation.
Mark
So what's the real story here?
Mimi
A church damaged by disaster is being preserved through digital means, and that same technology is opening up Italy's cultural treasures to people who might never visit in person. It's about access and resilience.
O Pulso
- Two earthquakes struck the Basilica of Saint Francis in 1997 within hours of each other, collapsing the roof, killing four people, and reducing irreplaceable medieval frescoes to dust and debris.
- Decades of painstaking manual restoration left eighty thousand fragments still uncatalogued in storage, with chief restorer Sergio Fusetti sometimes placing just a single piece in an entire day's work.
- A tech company has deployed robotic gigapixel cameras to build a precise digital twin of the basilica — a three-dimensional blueprint so exact it could guide reconstruction if disaster strikes again.
- AI software can now detect cracks, discoloration, and lifting paint layers across entire frescoes in minutes, compressing what would have taken human restorers years into a single session.
- The project is expanding beyond Assisi — virtual reality is already letting visitors walk through ancient Pompeii and explore forgotten Roman baths buried beneath a parking lot in Rome.
- The friars see the technology not as a replacement for the sacred but as a vessel for it, hoping the digital twin will carry the spirit of Saint Francis to more people than the basilica's stone walls ever could.
On a hilltop in Umbria where a saint once preached the beauty of poverty, a medieval basilica that survived seven centuries of human strife was nearly undone in seconds by the earth itself. Three decades after the 1997 earthquakes killed four people and shattered priceless frescoes into eighty thousand fragments, the Franciscan friars of Assisi have turned to artificial intelligence and gigapixel imaging to accomplish what human hands alone could not. It is an old story wearing new clothes — the impulse to preserve what is sacred, to carry memory forward across catastrophe — now entrusted not only to monks and restorers, but to algorithms and light.
On a hill in Umbria where Saint Francis's followers built one of Christianity's most sacred spaces, two earthquakes struck in 1997 and nearly brought seven centuries of endurance to an end. The roof caved in, four people died beneath falling stone, and a cloud of pulverized plaster carried the dust of medieval masterpieces down the aisles. Friar Giulio Cesareo was a student inside when it happened, and thirty years later, the slightest vibration still sends cold through him.
The restoration that followed was slow and humbling. Chief restorer Sergio Fusetti — himself a survivor — spent years cataloguing more than eighty thousand fragments in the storage rooms beneath the church, sometimes managing to place just one piece in a full day's work. The frescoes remained pockmarked. Walls stayed bare. Human hands had reached their limit.
Then Giovanni Borelli arrived with cameras that capture images in gigapixels — billions of pixels, far beyond anything a phone can record. Hundreds of thousands of photographs, stitched together, now form a three-dimensional blueprint of the basilica precise enough to guide reconstruction if catastrophe returns. Alongside the cameras, artificial intelligence analyzes cracks, discoloration, and lifting paint in minutes rather than years, and will help match the fragments still waiting in storage to their rightful places.
Borelli's ambitions reach further still. His company is using the same technology to unlock Italy's hidden past — forgotten Roman baths beneath a parking lot in Rome, ancient Pompeii rendered so vividly in virtual reality that visitors can stand at a party frozen two thousand years ago and watch musicians play. He imagines a future where students don't just read about great paintings — they walk inside them.
For Friar Giulio, the question of whether AI belongs in the custody of Saint Francis's legacy has a simple answer: the technology is a tool, not the goal. The goal is sharing a treasure of faith and beauty with more people than the basilica's stone walls could ever hold. The digital twin is expected to be complete next year — a new kind of pilgrimage, traveling not on foot, but through light.
On a hill in Umbria where gallows once stood, the Franciscan friars built one of Christianity's most sacred spaces. The Basilica of Saint Francis rose over centuries, its walls filled with the brushwork of medieval masters drawn to the story of a radical monk who rejected wealth for poverty. For seven hundred years it endured—war, fire, flood. Then, in 1997, two earthquakes struck one after another, and the great church nearly fell.
The roof caved in. A thick cloud of soot and pulverized plaster rolled down the aisles, carrying with it the dust of priceless art. Four people died under falling stone. Friar Giulio Cesareo was a student in the basilica when it happened. He watched a massive stone arch dance in the tremors, a sight he says people struggle to believe. Three decades later, he still feels cold creep through him at the slightest vibration.
The restoration that followed was grueling work. Pieces didn't fit. Frescoes remained pockmarked. Walls stayed bare. In the storage rooms beneath the church, Sergio Fusetti, the chief restorer and himself a survivor of the quakes, catalogued more than eighty thousand fragments—each one an irreplaceable part of a thirteenth-century masterpiece. He spent years trying to reassemble them, sometimes placing just one piece in a full day of labor. But the work reached a limit. Human hands and eyes could only go so far.
Then came the technology. Giovanni Borelli, the chief technology officer of Haltadefinizione, arrived with cameras unlike anything the friars had seen. These are not the cameras in phones. Borelli's robotic systems capture images in gigapixels—billions of pixels, three orders of magnitude beyond what a mobile device can record. Hundreds of thousands of photographs, stitched together, create a three-dimensional blueprint of the basilica so precise that if disaster strikes again, restorers will have an exact map to rebuild.
But the cameras are only the beginning. Artificial intelligence will do what Fusetti could not. The software can analyze cracks in paintings, discoloration, lifting layers of paint—work that would take a human restorer years to complete. With AI, Borelli said, it takes minutes. The technology will help fit together the fragments still waiting in storage, each one a puzzle piece with no certain home.
Borelli's ambitions extend beyond the basilica. His company is using the same ultra-high-definition scanning and virtual reality to open Italy's hidden treasures to the world. Beneath the streets of Rome, under a parking lot, lie the remains of Roman thermal baths with thirty-foot ceilings and delicate mosaics—chambers forgotten by history until the lasers revealed them. In Pompeii, visitors wearing VR headsets can stand at an ancient party, watching musicians play pipes and harps, watching wine flow, stepping into scenes that have been dead for nearly two thousand years.
Borelli speaks of a philosophical question that drives him: How good can a digital representation of a physical object be? What is missing? He admits the technology cannot yet duplicate the emotional weight of standing before an original work of art. But he imagines a future where students don't sit in rows listening to lectures about paintings—they walk inside them, fly around them, see them from angles no human eye ever could.
When asked if he had concerns about using artificial intelligence as a custodian for the legacy of Saint Francis, Friar Giulio Cesareo was clear. The technology itself is not the goal. It is a tool. The goal is sharing the treasure—a treasure of faith and beauty—with more people than the friars could reach before, and in a more efficient way. The digital twin of the basilica will be complete next year, available to the public. The friars hope it will carry the spirit of Saint Francis farther than it has ever traveled, both in the heavens and in the cloud.
