I know this blessed place is a human-made interpretation of what is mysterious, unknowable, and undefinable and while seeing her burn brings tears to my eyes, I know even flames cannot diminish her sacredness. Still, not her. Please. Not her. #notredame #ourlady".
Stassi Schroeder shared a happy shot of herself visiting the irreplaceable landmark. "I'm on a plane right now, feeling such an extraordinarily extreme sense of sadness. This photo was from the first time I visited Notre Dame as an adult."
"I hesitated to even post this photo since I look like an asshole IG influencer, but I have had a deep love for Paris, and Notre Dame is the heart of this city. Every time I've walked inside, I've felt like I was a part of history and my heart is fully breaking knowing that this monumental cathedral is being torn apart. We are so lucky to be able to preserve history whether it be art, architecture etc. Appreciate history when you have the chance, you never know what can happen. I want to ramble more, but I'm going to stop myself. #notredame."

Notre Dame is a symbol of our ability as human beings to unite for a higher purpose—to build breathtaking spaces for worship that no one person could have built on their own.
