In a speech delivered shortly before midnight, French President Emmanuel Macron implored the French people to join a national fundraising campaign to repair the damage, and at least one of the country's wealthiest men has already obliged.

French billionaire François-Henri Pinault said Monday night that he and his family would donate €100 million ($113 million) to the rebuilding effort. Pinault, who is chairman of Kerring group, the luxury goods powerhouse behind Gucci, Balenciaga and Yves Saint Laurent, said the money would come from his family's investment firm, Artemis.

In a statement, the billionaire, who is married to actress Selma Hayek, said he hopes that the money will help the Catholic Church "completely rebuild Notre Dame."

"My father [François Pinault] and I have decided to release as of now from the funds of Artemis a sum of 100 million euros to participate in the effort that will be necessary for the complete reconstruction of Notre Dame," he said.
