Built on the Île de la Cité during the Middle Ages, Notre-Dame Cathedral is an integral part of French history. The sacred presence of the cathedral, a major monument of Gothic architecture and an emblem of power throughout its existence, has never ceased to inspire the popular imagination. Indeed, Notre-Dame, the “mile zero” used to measure distances, is one of the nerve centers of France. On April 15, 2019, the burning of Viollet-le-Duc’s spire provoked considerable emotion around the world, providing a stark reminder that the building belongs to a shared heritage. Thanks to both traditional know-how and the latest technology, the restoration of Notre-Dame Cathedral has revived interest in its architecture and the history linking us to the living monument, the most visited in the world.
