Notre Dame appears structurally sound after fire, as investigators look for cause

A day after a monstrous fire roared through Notre Dame Cathedral, destroying its roof and lacy spire and leaving three holes in its sweeping vaulted ceiling, officials on Tuesday were trying to determine what caused the catastrophe.

The cathedral appeared to be structurally sound, officials said, after an inspection. With the fire extinguished, they now began what the Paris prosecutor, Rémy Heitz, told journalists would be “a long and complex investigation,” though for now he said they were considering the disaster an accident.

“Nothing at this stage suggests a voluntary act,” he said.

The Paris prosecutor’s office said Tuesday evening that investigators had questioned about 30 witnesses. These included workers from the companies involved in the restoration of the cathedral not long before the fire broke out, and staff at Notre Dame in charge of security.

The first fire alarm Monday was set off at 6:20 pm, and checks were carried out but no fire was found, Heitz said.

A second alarm went off at 6:43 pm, he said, and fire was discovered in the wooden framework of the attic, ancient beams beneath the lead roof known as the “forest.”

As investigators faced the difficult task of determining a cause in the apparent absence of evidence, destroyed by the roaring flames, officials, citizens and visitors continued to congregate on the banks of the Seine River to contemplate the mutilated monument, an unequalled jewel of Gothic architecture.

Frédéric Létoffé, co-president of a group of French companies that specialise in work on older buildings and monuments, said Notre Dame had fire detectors that functioned continuously and was equipped with dry risers — empty pipes that firefighters can externally connect to a pressurised water source.

But he said that the cathedral — like many others in France — did not have automatic sprinklers in the wooden framework of the roof, and that its attic space was not compartmentalised with fire-breaking walls, which could have prevented a blaze from spreading.

“It’s exposed to the sky — it’s an absolute tragedy, beyond anything we could have imagined,” said Stephen Bern, who has served as an adviser on France’s monuments to President Emmanuel Macron
