The loss of history and artifacts in the cathedral fire has prompted global grief. The main structure and two towers were saved, however. French President Emmanuel Macron has vowed to rebuild the church. /VCG Photo

Over one billion U.S. dollars has been raised around the world in efforts to save and repair the cathedral, according to the Washington Post. /VCG Photo
