On the evening of April 15 2019, France and the world watched transfixed in horror as flames ravaged Notre-Dame cathedral in Paris, fearful that the heritage landmark could be lost to humanity forever. While the spire collapsed and much of the roof was destroyed, the efforts of firefighters ensured the great mediaeval edifice survived the night. Yet the road to restoration has been long and arduous and it is only expected to return to its former glory in April 2024, five years after the fire.
