A huge crane and renovation teams worked at the site Thursday, after authorities warned that some of the structure remains at risk. Firefighters walked on what the remains of the roof to inspect damage.

The island housing Notre Dame at the heart of the French capital remained largely empty Thursday and closed to everyone but residents. Businesses were shuttered and the usual tourist throngs were nowhere to be seen.

Passersby praised the French firefighters who helped save the overall structure of the cathedral, although its spire collapsed and its roof was destroyed in Monday’s devastating fire.

France is paying a daylong tribute Thursday to the Paris firefighters who saved the internationally revered Notre Dame Cathedral from collapse and rescued its treasures from encroaching flames.

French President Emmanuel Macron will host the firefighters for a special gathering to share “words of thanks.” Top government ministers will also take part in the event at the presidential palace in Paris.

Later, Paris City Hall will hold a ceremony in the firefighters’ honor, with a Bach violin concert, two giant banners strung from the monumental city headquarters and readings from Victor Hugo’s “The Hunchback of Notre Dame.”

Remarkably, no one was killed in the fire, which occurred during a Mass, after firefighters and church officials speedily evacuated those inside.
