A catastrophic fire engulfed the upper reaches of Paris' soaring Notre Dame Cathedral as it was undergoing renovations on Monday, 15 April, threatening one of the greatest architectural treasures of the Western world as tourists and Parisians looked on aghast from the streets below.

The blaze collapsed the cathedral's spire and spread to one of its landmark rectangular towers. A spokesman said the entire wooden frame of the cathedral would likely come down, and that the vault of the edifice could be threatened too.

The cause of the blaze was not known, but French media quoted the Paris fire brigade as saying the fire is "potentially linked" to a 6 million-euro ($6.8 million) renovation project on the church's spire and its 250 tons of lead.

Prosecutors opened an investigation as Paris police said there were no reported deaths. Some 400 firefighters were battling the blaze well into the night.
