According to him, the stone walls are still saturated with water which was sprayed by firefighters during the fire on April 15.
Villeneuve underlined that the walls can dry too fast amidst the record temperatures expected in Paris this week.
“I’m afraid that the joints or the masonry, as they dry, lose their cohesion... and all of sudden, the vault gives way,” the architect said.
As it was reported earlier, Notre Dame Cathedral caught fire in Paris this evening. According to the press, the fire began at the roof of the cathedral on Monday. The fire occurred due to maintenance works on the spire. The witnesses are posting videos and photos on social networks from the scene. The sick smoke raises up and it is seen from the different regions of Paris.
President Emmanuel Macron promised that Notre Dame would be restored within five years. At the same time, the French restorers claimed it would take up to 10-15 years in order to restore the monument.
