Catholic authorities collaborated with Microsoft to develop a digital twin of St. Peter's Basilica, one of the most important Christian churches and a globally renowned tourist

Every nook and cranny of Saint Peter's Basilica will soon be laid bare thanks to artificial intelligence and a trove of 400,000 photos of the celebrated Vatican monument, according to a project presented Monday.

The heart of the project is the creation of a digital twin of St. Peter’s Basilica through advanced photogrammetry and artificial intelligence that allows anyone to “visit” the church and learn about its history.
