St. Peter's Basilica in Rome, the largest Catholic church in the world, exposed by artificial intelligence

In addition to the virtual discovery of the monument, the site will also offer to book a visit depending on the number of visitors, while millions of pilgrims are expected in Rome for the jubilee of 2025, a holy year proclaimed by Pope Francis.

The smallest nooks and crannies of Saint Peter's Basilica in Rome will be exposed on a virtual portal thanks to the exploitation of 400,000 photos of the monument by artificial intelligence (AI), according to a project presented Monday November 11, 2024 at the Vatican .

From December 1, Internet users will be able to discover on the basilica website a reconstruction of the evolution through the ages of the basilica, from the Roman era to the current basilica. In addition to this site, exhibition rooms set up inside the basilica will allow visitors to immerse themselves in its history. The portal will also offer a virtual tour of this monument, which will celebrate its 400th anniversary in 2026, with the possibility of exploring both the Vatican grottoes and the dome crowning the building.

To bring this project to fruition, the Vatican enlisted the services of the American company Microsoft which, based on several hundred thousand photos taken by drones, reconstructed the smallest details of the architecture, paintings and sculptures. . This work, which required two years of work, allowed the construction of a “digital twin”rejoiced during a press conference Brad Smith, vice president of Microsoft, welcoming “one of the largest projects of its kind”. AI has made it possible to exploit “the enormous amount of information” contained in the 400,000 photos taken by the drones to reconstruct this “giant patchwork”he added.

The project aims to “decode for contemporary man, with the help of digital technologies, the intertwining of history, art and spirituality, which make the basilica a unique place in the world”explained for his part the archpriest of the basilica, Cardinal Mauro Gambetti.
