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

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.

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.
