French President Emmanuel Macron has told workers who revived Paris' iconic, fire-ravaged Notre Dame cathedral, that they "achieved what was thought impossible."

Visiting the cathedral, Macron tells workers they healed 'national wound' with renovation work costing hundreds of millions of euros after 2019 blaze

You’ve achieved what was said to be impossible,” the French president told workers at the Paris monument, which will reopen after the 2019 fire.
