Michelle Obama: 'I know that Notre Dame will soon awe us again'

Michelle Obama honored Notre Dame Cathedral on Monday after much of it was destroyed in a massive blaze, saying the historic Paris cathedral "will soon awe us again."

The former first lady made the comment on Twitter, sharing a photo first posted by her husband, former President Obama.

"The majesty of Notre Dame-the history, artistry, and spirituality-took our breath away, lifting us to a higher understanding of who we are and who we can be," she wrote. "Being here in Paris tonight, my heart aches with the people of France. Yet I know that Notre Dame will soon awe us again."

Obama is in Paris for a tour stop to promote her new memoir, "Becoming."

Her voice adds to thousands around the globe mourning the loss of history after a fire tore through the famous cathedral at the heart of Paris.

Law enforcement officials have launched an investigation into the cause of the fire, which is currently being treated as an accident and possibly linked to restoration work being done on the cathedral.

French President Emmanuel Macron expressed sadness over the fire earlier in the day.

"Notre-Dame is aflame. Great emotion for the whole nation. Our thoughts go out to all Catholics and to the French people. Like all of my fellow citizens, I am sad to see this part of us burn tonight," he tweeted.

Officials originally worried the entire structure would burn but later announced that the main structure and bell towers had been saved.
