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

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.

French President Emmanuel Marcon, his wife and a select number of people were given a tour of Notre-Dame Cathedral on Friday, as it is set for a grand reopening to the public next week after hundreds of millions were poured into a renovation following a devastating early 2019 fire.
