Notre Dame, which welcomed 12 million visitors in 2017, expects to receive an even higher figure of 14 to 15 million after the reopening, according to the church authorities.

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

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.
