Notre-Dame Cathedral fire and reconstruction (2019-2024)
A fire destroyed the roof and spire of the 12th-century cathedral in Paris. France pledged to rebuild, and more than $900 million was raised.
The cathedral closed for five years.
It reopened in December 2024 with a restored interior and new safety systems.
Shows that fire-damaged landmarks can take years to rebuild, with preservation and modern safety shaping the result.
