Italy has also played a role in the "new" Notre-Dame in Paris. Many Italian companies and talents contributed to the massive five-year restoration project, which involved over €700 million in funding. Florentine architect Carlo Blasi oversaw the structural stability analysis, consolidation of damaged vaults, and reconstruction of collapsed ones. His research was instrumental in proving that the cathedral's stability could be guaranteed by rebuilding it in accordance with its original configuration. This decisively impacted the restoration approach and the structural integrity of the structures. At the same time, Livio De Luca, a Calabrian engineer and architect, oversaw Notre-Dame's digital construction site, allowing for the creation of a three-dimensional model that used scientific data, laser surveys, and images to plan and monitor each aspect of the restoration process. The Italian company Mapei provided innovative materials and technical solutions for vault consolidation. What visitors and worshippers now see as they return to Notre-Dame includes the 18th-century Neapolitan Nativity Scene. This display features over 100 figures, including shepherds and animals, from the collection of Alberto Ravaglioli. It was curated by Biagio Roscigno, a sacred art restorer and Nativity scene designer. The Neapolitan Nativity Scene will be on display at Notre-Dame until February 2.
