US President-elect Donald Trump will attend the weekend reopening of the restored Notre Dame cathedral in Paris, which was ravaged by a 2019 fire, he said Monday.

The 850-year-old edifice will welcome visitors and worshippers again this Saturday and Sunday, with several world leaders expected among the guests, after a sometimes challenging restoration.

"It is an honor to announce that I will be traveling to Paris, France, on Saturday to attend the re-opening of the Magnificent and Historic Notre Dame Cathedral, which has been fully restored after a devastating fire five years ago," Trump wrote on his Truth Social network.

French President Emmanuel Macron conducted an inspection of the restoration of the medieval cathedral on Friday, saying workers had done the "impossible" by healing a "national wound."
