The fire broke out in the "forest of Notre-Dame", one of the treasures of the cathedral, a marvel of Gothic architecture (second half of the Middle Ages) that was not usually part of the sites visited by the nearly 12 million tourists received each year.

The forest was an immense structure located on the roof of the cathedral, 100 meters long and 13 meters wide in the nave and 10 meters high, built in oak. This frame consisted of about 1,300 beams, each from a different tree. It is therefore estimated that for its construction, it was necessary to cut at least 21 hectares of forest. That's where his name comes from. It is estimated that some of the trees from which they originated could be between 300 and 400 years old, which means that they dated from the 8th to the 9th century.

This wooden structure supported a roof built with approximately 1325 lead sheets 5 mm thick, weighing 210 tons.

According to the official page of the cathedral, in 1196, Bishop Maurice de Sully bequeathed in his will 5,000 pounds sterling for the purchase of lead for the roof of the temple. One of the advantages of this layer of lead is that it perfectly seals the surface of the structure, according to the National Library of France. According to the architect of the cathedral, Patrick Chauvet, fire inspectors regularly monitor the building, including the wooden roof, of which they check the condition three times a day.

Frédéric Létoffé, director of a French group specializing in the restoration of buildings and ancient monuments, explained that the cathedral was equipped with smoke detectors, but that there were no automatic sprinklers in the forest area because they never wanted to install an electrical system because of the risks of a short circuit.

According to Vincent Dunn, a fire safety consultant interviewed by The New York Times, religious sites are a challenge for firefighters. "These cathedrals and worship centers are built to burn – if they were not places of worship, they would be closed," he said.
