The refurbishment of the 800-year-old symbol of French history and culture of now nearly 90% complete, showing off gleaming new stone, freshly laid tiles and revamped paintwork.
And the roof and spire, which millions around the world watched crash to the ground in the 2019 fire, are now almost finished.
ABC's Foreign Correspondent James Longman first stood on the roof in 2021 and saw up close the gaping hole still open to the elements. When he went back in December 2023, the pieces were coming together.
One year from reopening, 'GMA' views Notre Dame's new spire
But now, the scaffolding from the spire is nearly gone and tiles cover the timber, a sign of hope and progress.
"We have finished the work of the wood to build this spire, and now we work on the roof," said Philip Jost, head of restoration.
It's a colossal project with a massive undertaking. Two thousand workers, from carpenters to artists to metalworkers, are making these changes to meet the December 2024 deadline for reopening and it's no easy feat.
Jost says the cost so far is 700 million euros, with the team in the final stretch.
"People will come to the games and they will see the spire and the roof, the opening of the cathedral," said Jost.
Notre Dame will only be a spectator to the opening ceremony of the summer Olympic games in Paris, which will run just outside of the cathedral along the river Seine, but it's own unveiling in December promises to be just as spectacular.
