PARIS (CNS) — A major blaze engulfed the iconic Notre Dame Cathedral April 15, sending pillars of flame and billowing smoke over the center of the French capital.

The fire erupted about 6:30 p.m. local time, and authorities said the cause was not certain but that it could be linked to renovation work that the cathedral was undergoing, the BBC reported.

Officials ordered an evacuation of the area around the 850-year-old cathedral that has withstood world wars and political turmoil throughout France’s history.

Le Monde, a Paris daily newspaper, reported that the fire erupted in the attic of the cathedral. Televised images showed the church’s iconic steeple was ablaze.

In 2018, the Catholic Church in the Archdiocese of Paris opened an urgent fundraising appeal to save the cathedral, which was starting to crumble.

The Associated Press reported that Paris Mayor Anne Hidalgo said about an hour after the fire started that firefighters were attempting to contain a “terrible fire” at the cathedral. An AP reporter at the scene said the roof at the back behind the cathedral, behind the nave, was in flames and yellow-brown smoke and ash filled the sky.

City officials cordoned off the area around the Gothic-style church and urged people to evacuate the immediate surroundings.
