After a fire tore through Notre Dame in Paris on Monday, with the spire and rooftop of the 850-year-old Gothic cathedral going up in flames, officials in France and individuals around the world began to sketch out a plan to restore the edifice. French President Emmanuel Macron said on Tuesday he wants Notre Dame rebuilt within five years, though a restoration expert said the work could take 10-15 years. The iconic rose windows and two main towers survived, and donors — including French billionaires, major businesses, and the University of Notre Dame in Indiana — have already pledged more than $1 billion to reconstruct the destroyed portions of the cathedral. Police believe the fire was started by accident, perhaps related to ongoing renovation work.
