What burned, what was saved (the crown of thorns of Jesus Christ was not injured), whether the building can be restored and how much money it is going to do - collected the key facts known about the tragedy in Paris at the moment.
On April 15, a fire broke out in Notre Dame, which lasted almost nine hours. The roof, spire and clock of the temple collapsed, but the frame of the building was saved. The French President promised to restore the cathedral and announced a fundraiser.
On April 15, at about 19 o'clock local time (about 20 Moscow time) in the Cathedral of Notre-Dame de Paris - one of the main churches of France and the Roman Catholic Church - the fire started ( https://esquire.ru/articles/95432-v-parizhe-gorit-sobor-parizhskoy-bogomateri/) . It lasted almost 9 hours. He managed to extinguish only by the morning of April 16. UPD: according to other information (according to the French Ministry of Internal Affairs), the fire continues, but is under control ( https://tass.ru/proisshestviya/6337870 ) .
The exact cause of the fire has not yet been named. It is known that reconstruction works were carried out in the cathedral. Initially, the flame originated in the area of scaffolding installed above the roof.
An hour later, a spire and a clock collapsed against a building built in the 12th — 14th centuries. The entire roof collapsed. Only after that the authorities and firefighters began to take active steps to eliminate the fire. The representative of the cathedral admitted the likelihood that the cathedral is likely to fail to be saved, since the floors in the building are wooden and have stood for 850 years, however, it was reported that the supporting structures still survived.

At first, the firefighters could not cope with the fire, because the equipment was not enough to get to the fire spire: because of the shape of the structure and its height, the hoses and ladders simply did not reach the roof, and it was impossible to drop water from the helicopter she could damage the surviving parts of the building.
French President Emmanuel Macron and Prime Minister Edouard Philip arrived at the site of the fire. The prosecutor's office launched an investigation into an article about the unintentional damage caused by a fire in the cathedral. While law enforcement officers do not see the criminal component in connection with the incident.
A security perimeter was established around the cathedral. Authorities evacuated residents of the island of Cite, where the cathedral is located. However, Parisians and tourists still flocked from all over the city. Some of them prayed, someone silently wept. ( https://ria.ru/20190415/1552718514.html )
The fire did not affect a number of sacred objects. Including relic, revered as the crown of thorns of Jesus Christ. Also managed to save the altar and the altar cross.
Emmanuel Macron announced that the temple would be restored and announced a fundraiser for restoration work. "We will turn to the greatest talents and restore Notre Dame, because this is what the French expect, because this is what our history deserves." Perhaps the restoration of the cathedral will take at least a dozen years.( http://www.lefigaro.fr/actualite-france/2019/04/15/01016-20190415LIVWWW00055-en-direct-incendie-notre-dame-de-paris.php )
The French businessman Francois-Henri Pinault, owning large companies Artemis and Kering, has already donated 100 million euros.
The European Union declared that it was ready to render any assistance to France: to provide specialists, equipment, transport and other resources. ( https://tass.ru/proisshestviya/6337610 )
I think that there is a great loss for the whole Franzu people and the symbols of architecture. Also, the cathedral is one of the symbols of Paris, and many guys who traveled through the program of the European Solidarity Corps, laid out a photo on the background of Notter Dame. What to say, in my opinion, the Hunchback will have to look for a time rented accommodation. Does anyone know who rents the bell tower?)
