Following an enormous, expensive restoration effort after the devastating 2019 fire, the Paris cathedral has reopened to the world, at once recognizably itself and possessed of a startling new vibrancy.

Dame cathedral will reopen, five years after a fire the storied medieval landmark will reopen its doors once again.

The word "Merci" was projected on to the front of Paris' Notre-Dame cathedral as it reopened on Saturday, in thanks for its salvation after a devastating fire that brought the 860-year-old building close to collapse five years ago.
