The restoration project mobilized roughly 2,000 craftspeople, including stonemasons, carpenters, sculptors, and organ builders, who worked to restore the 12th-century Gothic masterpiece after a devastating fire in April 2019.
The renovation included cleaning 42,000 square meters of stone, restoring 8,000 organ pipes, rebuilding the wooden framework roof known as 'the forest,' and reconstructing the 96-meter-tall spire that collapsed during the fire.
The modernization efforts and rapid reconstruction timeline may have compromised the cathedral's historical authenticity, with some original medieval elements lost forever and new materials and techniques potentially altering the building's character.
