A picture taken on April 16, 2019 shows the altar surrounded by charred debris inside Notre Dame Cathedral in Paris in the aftermath of a fire that devastated the historic cathedral. French investigators probing the devastating blaze on April 15 questioned workers who were renovating the monument, as hundreds of millions of euros were pledged to restore the centuries-old masterpiece. As firefighters put out the last smoldering embers, a host of French billionaires and companies stepped forward with offers of cash worth around 600 million euros ($680 million) to rebuild the iconic structure.
