Cries of horror can be heard in the videos as the structure falls.
Although the construction on the cathedral began in 1163, the first spire — flèche — wasn't added until around 1250, per the monument's official website.
The original structure housed five bells and stood for nearly 500 years until it was deemed unstable and dismantled in a process that lasted from 1786 to 1792.
A new spire was commissioned as part of the cathedral's massive 25-year restoration project, which began in 1844 and was helmed by Eugène Viollet-le-Duc.
The architect decided to re-create the original medieval structure. The new structure was built out of oak wood covered in lead and weighed 700 tons.
The structure was decorated with statues of the 12 Apostles and the traditional symbols of the four evangelists.
The spire marked the highest point of the cathedral and stood 295 feet above the ground.
These copper statues were removed last week as part of a new 6 million euro ($6.8 million) renovation project on the spire.
The cause of the fire is currently unclear and the full extent of the damage to the cathedral remains to be seen.
