French President Emmanuel Macron vowed to rebuild Notre Dame Cathedral after a massive fire tore through the centuries-old church on Monday.
Restoring the iconic cathedral would likely be complicated, lengthy and expensive, experts said.
But they also appeared optimistic that such a rebirth is possible.
Jonathan Foyle, an architectural historian and author, said a critical part of the restoration process will be to assess how damaged Notre Dame’s massive stone vaults were by the blaze. Extreme temperatures can cause calcination — a process that turns stone into powder, he said.
