Paris Mayor Anne Hidalgo said in a tweet that major art pieces and sacred items from Notre Dame were saved from the fire.

"Thanks to the @PompiersParis, the police and the municipal agents," Hidalgo tweeted, "the Crown of Thorns, the Tunic of Saint Louis and several other major works are now in a safe place."

The cathedral is home to numerous artifacts, works of art and religious relics, each telling a story.

After the devastating fire tore through the cathedral on Monday, toppling its spire, many feared the items -- collected over the centuries -- might be lost. It was unclear how many had been saved.
