A devastating fire swept through Notre-Dame cathedral in Paris Monday evening, severely damaging one of the city’s most storied landmarks and one of the Catholic world’s most sacred sites.

The blaze, which started Monday evening, caused the church’s spire to collapse and ruined two-thirds of its roof. By Monday night, firefighters said the church’s overall structure had been saved, and its two towers, perhaps its most recognized feature, would withstand the effects of the fire.

The cause of the fire, in which no one was injured, was not yet known.

Here are photos from the scene of the blaze:
