It looks very, very bad.

I think they might lose it. No water on it yet, according to the news. Horrible.

I am crying. This is horrible. Notre Dame is Paris,

End of the world.

This is so horrible!!!

On the verge of tears. What a tragedy.

This is so sad and terrible.

Devastating.

i have no words. 35 years ago when i went to Paris for the first time, the first thing i saw was Notre Dame. I cried then, and i'm crying now. The whole world is going crazy.

I just saw the news. It's heartbreaking. I remember my first glimpse of Notre Dame, and it was the most incredible sight. Much more so than the Eiffel Tower for me at that time.

This is the second fire of a church in Paris within the month or so -- What's going on? -- so horrible

this is tragic... I'm so sad

I am glued to CNN watching this tragedy in Paris. So very sorry this is happening....such history, beauty, and significance. A terrible loss to a a world in need of beauty and awe.

Beyond devastating. I think I'm having a bad dream.

Oh my God, I just saw the videos. The spire has collapsed. This 12th century building is stone atop wooden frame. It is, unfortunately, gone, no doubt the victim of the renovations meant to protect it.

My last memory was of a Remembrance Day, listening as the bells of Notre Dame rang the changes at 11:00. To have come through two wars and now this. It is heartbreaking.
