Too early to know cause for sure but may be linked to restoration work that was being done. Main spire and roof of cathedral is gone........tragic. All that lead being liquified is another health concern.
When I was there, more than 20 years ago, I thought it the most beautiful, awe inspiring building I had ever seen. This is so sad. I was certain I was going there again. It is a major national symbol for France, and even more for parisians. So sad. It really makes me feel that nothing lasts forever.
Very sad news. My wife and I visited Paris last September for our 40th anniversary.
One evening as we walked along the Seine we stopped and watched an elderly gentleman paint with watercolors. We chatted with him for about 15-20 minutes as he painted. He was a wonderful charming man. We purchased two watercolors from him, one is of Notre Dame Cathedral. We had the watercolors framed and they're great reminders of the great trip we had.
Here is the Notre Dame Cathedral watercolor.
This is such sad news. I never had the priveledge of seeing it firsthand and now it is doubtful that my kids will get the chance either.
That said, I agree that it will be rebuilt. I was surprised to read how much of the building that existed prior to the fire had been started or updated in the last 225 years or so. This gives me hope that it will rise from the ashes again.
