Friars at the Basilica of Saint Francis of Assisi are working with art historians and technology company Haltadefinizione to build a detailed digital twin of the historic church. Cameras, drones and lasers are collecting hundreds of thousands of images that will form a three-dimensional blueprint and a reconstruction guide in the event of another earthquake. The team also plans to use AI to help place some of more than 80,000 fragments and analyze damage to paintings. The digital twin is expected to be complete next year and available to the public. The report does not state the project’s cost or explain access rules for the underlying restoration data.

TLDR: A digital model of Assisi’s Basilica of Saint Francis is intended to help restorers document the building and respond to future earthquake damage. The public version is expected next year, while AI may assist with fragments and art analysis.

Nearly three decades after earthquakes damaged the Basilica of Saint Francis of Assisi, restorers still face a task that has resisted years of careful work: identifying where more than 80,000 fragments of the 13th-century church belong. A new project is bringing friars, art historians and software engineers together to use detailed digital images and artificial intelligence in the continuing restoration. The tools are meant to help document the basilica and support future work, not replace the people responsible for it.

The practical reason for the project is clear. A digital record can give restorers a detailed reconstruction guide if another earthquake damages the building, while AI may help sort fragments and assess problems in paintings more quickly than a person working by hand. Friar Cesareo has described the larger aim as sharing the basilica’s “treasure of faith and beauty” with more people and in a more efficient way.

The basilica stands in the hills of Umbria in central Italy and is the resting place of Saint Francis. Its walls hold works by medieval artists including Cimabue, Pietro Lorenzetti, Simone Martini and Giotto, who painted scenes from Francis’s life. The building has endured more than 20 earthquakes, according to Sergio Fusetti, who has worked on its art restoration since the 1970s.

Two powerful earthquakes struck one after another in 1997 and damaged part of the roof. Falling rubble killed four people, and Fusetti was hospitalized after being injured in the second quake. Restorers painstakingly repaired frescoes and other art, but the work remains incomplete: some frescoes are still pockmarked, some walls are bare, and more than 80,000 fragments have not been matched to their original locations.

That unresolved puzzle is one reason Fusetti said artificial intelligence could help. Friars are working with Haltadefinizione, a company that specializes in ultra-high-definition photography. The company’s chief technology officer, Giovanni Borelli, is leading the effort to create a digital twin, or detailed digital representation, of the basilica.

The team is using cameras, drones and lasers to collect hundreds of thousands of images. The equipment can record details that are difficult to see with the human eye, including brushstrokes and other features of the artwork. The images will be combined into a three-dimensional blueprint described in the source report as the highest-resolution 3D blueprint of a building ever made.

That record is intended to serve a practical purpose as well as a historical one. If another earthquake strikes the area, restorers would have an exact reconstruction road map to consult. The digital twin is expected to be complete next year and will be available to the public. The project therefore offers a way to preserve detailed information about the building while also widening access to its art.

Borelli’s team also plans to use AI to help fit some missing pieces into the church and examine damage such as cracks, discoloration and lifting paint. Borelli said a full round of that kind of analysis by people working with their eyes and hands could take years, while AI could complete it in minutes. That is a comparison of speed, not a claim that software can make every restoration decision. The source does not specify how AI-generated matches will be checked or who will make final judgments about repairs.

The technology has limits. Borelli has acknowledged that virtual reality cannot reproduce the emotional effect of standing in front of a historic work of art. Still, digital experiences can let users explore parts of Italy’s past from elsewhere. Similar technology has been used to record the remains of a Roman emperor’s thermal bath, where laser scanning captured rooms with 30-foot ceilings and delicate mosaics, while cameras revealed hidden chambers and passageways.

The practical details reported so far are specific about equipment and timing but limited in other areas. The team is collecting images with cameras, drones and lasers, and the public version of the basilica’s digital twin is scheduled for completion next year. The report gives no project cost, application forms, access fees, compliance rules or enforcement process. It also does not explain who will control access to the underlying restoration data beyond saying the completed digital twin will be public.

The next step is completion of the digital model, followed by its planned public availability next year. AI-assisted analysis and the work of matching fragments remain part of the restoration effort, while questions about review procedures and data control are not detailed in the report. The project’s stated aim is to preserve the basilica’s art and make it accessible to more people; the results and the promised public access will provide the next points to watch.
