Project Aims to Preserve and Share the Architectural Legacy of France’s Most Visited Landmark
Microsoft has announced a partnership with the French government to build a digital replica of Paris’ iconic Notre-Dame Cathedral. The initiative, revealed on Monday by Microsoft President Brad Smith, will digitally document the 862-year-old monument’s intricate architecture while making it accessible to virtual visitors around the world.
The Gothic cathedral, which reopened in December 2024 after a five-year restoration effort following the 2019 fire, remains one of the most visited monuments in France.
A High-Tech Archive for Future Generations
Microsoft stated that the digital twin will serve both as a virtual experience for those unable to visit and as a precise architectural record for future reference. The technology giant emphasised the long-term value of such preservation, noting that the data could support conservation work for generations to come.
“One of the things we learned from the work at St Peter’s is how a digital twin can help support the ongoing maintenance of a building,” Smith said in an interview with Reuters. “Because you capture a digital record of every centimetre and what is there and what it’s supposed to look like.”
Smith added, “The ability to create a digital twin right now, I think, will provide an enormously valuable digital record that I believe people are going to be using 100 years from now.”
Quasimodo’s Home Goes Digital
Notre-Dame Cathedral has long held symbolic and cultural importance for France, amplified by Victor Hugo’s 1831 novel The Hunchback of Notre-Dame. The book’s hunchbacked bell-ringer, Quasimodo, has been immortalized in films, animation, and musicals, reinforcing the cathedral’s legendary status.
Building on Past Digital Preservation Work
Microsoft previously collaborated with French digital heritage company Iconem on a virtual replica of St Peter’s Basilica in Vatican City. The company has also preserved other heritage landmarks and moments since 2019, including:
- Ancient Olympia in Greece
- Mont Saint-Michel in France
- The 80th Anniversary of the Allied Beach Landings in Normandy
These efforts reflect a broader commitment to using cutting-edge technology to preserve cultural heritage worldwide.
