"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," Pinault said in a statement.

Pinault is the owner of the French luxury group Kering based in Paris. The luxury group owns brands including Gucci, Saint Laurent, and Alexander McQueen, among others. He is also the husband of Mexican American actress Salma Hayek.

The blaze broke out at approximately 7 p.m. on Monday, and authorities say a preliminary investigation indicates it was accidental. The cathedral’s 300-foot spire was destroyed in the fire, but officials said the cathedral's iconic twin bell towers will stand.

French President Emmanuel Macron said the cathedral would be rebuilt and announced that he would unveil a national fundraising campaign to fund the effort.

"We will rebuild," Macron said Monday. "We will rebuild Notre Dame because this is what the French expect, because this is what our history deserves, because it is our destiny."
