St. Peter’s Basilica, one of the largest places of pilgrimage, receives about 15 million visitors annually. It is famous for its Renaissance and Baroque architecture, with contributions from famous artists such as Michelangelo and Bernini. T
he Fabbrica di San Pietro, a Catholic foundation responsible for the preservation and maintenance of St. Peter’s Basilica, has partnered with Microsoft to create a “digital twin” of the Basilica. This highly accurate virtual representation allows pilgrims and visitors to virtually explore the structure.
To carry out this project, Microsoft collaborated with Iconem, a leader in the field of digital preservation, known for creating 3D replicas of the world’s most famous historical monuments and archaeological sites. Microsoft used Azure, photogrammetry and AI to create a highly accurate virtual representation of St. Peter’s Basilica.
The Iconem team captured over 400,000 high-resolution images using advanced photogrammetry techniques. They spent three weeks scanning the Basilica with various devices, including drones, cameras and lasers. The huge amount of images collected was processed using the Microsoft Azure cloud platform. The AI-generated images, derived from Iconem’s photogrammetry data, enhanced the depiction of both the interior and exterior of the Basilica.
Microsoft’s AI for Good Lab contributed advanced tools to improve the digital twin with millimeter accuracy. Artificial Intelligence was also used to help identify and map structural vulnerabilities such as cracks and missing mosaic tiles, helping the Basilica authorities with repair work. An upcoming interactive website and immersive exhibitions will allow anyone to experience St. Peter’s Basilica both digitally and in person. This innovative project supported by Microsoft preserves the historical and architectural heritage of St. Peter’s Basilica while making it more accessible to people around the world.
Through the power of Technology, visitors can now experience the majesty and artistry of this iconic landmark in exciting new ways.
