Preview

In November 2024, a Vatican-overseen collaboration with Iconem and Microsoft presented a digital twin of St Peter’s Basilica built with photogrammetry and AI, delivered through an interactive website and immersive exhibitions. Microsoft reports more than 400,000 high-resolution images and AI tools that helped identify and map cracks and missing mosaic tiles. Image count measures capture scale, not audience impact, and the cited account does not establish conservation savings or increased participation. This Immersive Live brief separates public exploration from custodial documentation, keeps partner claims in scope and offers an original sacred-heritage pilot guided by custodians with access, interpretation and capture-quality measures.

What you will learn

  • Heritage twins can support both public exploration and condition mapping—if governance stays with custodians.
  • Capture scale is not audience impact; partner AI findings still need conservation review.
  • Policy, reverence guidelines and accessibility belong in phase zero of any sacred-site digitization.

Reported outcome. Microsoft reports capture of more than 400,000 high-resolution images and AI tools that helped identify and map cracks and missing mosaic tiles.

Image count measures capture scale, not audience impact. The cited account does not establish conservation savings or an increase in participation.
