The restoration of Notre-Dame Cathedral, severely damaged by a devastating fire on April 15, 2019, has been significantly enhanced by cutting-edge technology.
The blaze, which destroyed the cathedral's iconic spire and much of its roof, also caused extensive damage to its interior. The fire marked a tragic moment for one of the world's most beloved Gothic landmarks, sparking a global outpouring of grief and an urgent commitment to rebuild.
Advanced tools, including high-precision 3D scanners, have played a critical role in the restoration process.
These scanners meticulously documented the entire monument, enabling more precise restoration work and creating a comprehensive digital archive for future conservation efforts.
Mexican architect Alejandro Arredondo of AGP (Art, Graphique & Patrimoine), one of the experts responsible for 3D modeling, highlighted the scope of the project.

"We used high-precision 3D scanners to capture every detail of the monument. The scans covered the exterior, all interior spaces, and even the roof of the cathedral," he said.
To access hard-to-reach areas damaged by the fire, the team employed drones, which complemented the ground-based scans.
"This combination of tools allowed us to survey the structure quickly and thoroughly by placing the scanner at various strategic points," Arredondo explained," he added.
Over 2,000 scanning positions were meticulously recorded during several survey campaigns, resulting in an invaluable digital database.
This archive not only informs the ongoing restoration but also ensures that Notre-Dame’s architectural and historical details are preserved for future generations.
These efforts are part of a broader mission to restore the cathedral to its former glory while safeguarding its legacy after one of the most significant architectural tragedies in recent history.
