Luxury goods tycoons and major corporations cited national pride and culture in making the pledges.
French billionaires and major companies have pledged to donate at least 600 million euros to help reconstruct the Notre Dame Cathedral after a catastrophic fire tore through the historic structure, collapsing its spire, and causing significant damage.
Their donations came as Paris firefighters declared Tuesday morning that the fire had been fully extinguished.
"A group of experts are analyzing all of the structures to establish the next stages," Paris fire brigade spokesperson Gabriel Plus told reporters.
François-Henri Pinault, chairman and CEO of the international luxury group Kering, which includes Gucci and Saint Laurent, said Monday night that he and his family will donate 100 million euros to the cathedral's reconstruction.
