The Cathedral’s famous spire will be fully restored by the end of the year and an exact copy of the 96-meter high spire designed and built by 19th century architect Viollet-Le-Duc.

The spire is made from an oak wood structure and lead covering. Its 80-tonne wooden base, resting on stone arches 30 meters above the heart of the cathedral, is due to be completed on Saturday — four years since the fire that shocked the world.

The cathedral is due to reopen by the end of 2024.
