Notre-Dame, or the Notre-Dame Cathedral (French: Notre-Dame de Paris), is a famous Gothic-style cathedral located on the Île de la Cité in Paris, France. The structure was heavily desecrated and burgled during the tumultuous French Revolution.
Construction on the Notre-Dame began in 1163 and lasted for more than a century before it was completed in 1250. It would then undergo numerous changes over the next century. The cathedral was one of the first buildings in Europe to use flying buttresses, which allowed for much higher and thinner walls around the choir and the nave. They also provided the support necessary for the inclusion of the Notre-Dame's rose windows.
In 1791, the Templar Charles Gabriel Sivert arranged a meeting with his associate Duchesneau, which was to take place in Notre-Dame while Mass was being held. To accomplish this, his men stole the cathedral's master keys from one of the priests and positioned themselves throughout the building. However, the Assassin Arno Dorian managed to reclaim the keys and gain access to Notre-Dame, where he assassinated Sivert as the latter waited in a confessional booth.
Arno would later discover a secret laboratory beneath the cathedral which had been used by the noted alchemist Nicolas Flamel. During the Revolution, many of Notre-Dame's relics were stolen by the Templars, who used the nearby Hôtel-Dieu's sewer system to smuggle them away from the cathedral. In response, the Parisian Brotherhood sent agents to recover the artifacts and return them to Notre-Dame.
By 1793, the dechristianization of France was in full effect, with the Notre-Dame being rededicated to the Cult of Reason and later the Cult of the Supreme Being. The newly appointed National Guard were formally established during a benediction at the cathedral. Many of Notre-Dame's greatest treasures were subsequently looted and the statues of the biblical Kings of Judah were decapitated, having been mistaken for statues of the Kings of France; the cathedral's great bells managed to survive unscathed, however. Afterwards, Notre-Dame ended up being used as a storage facility for the troops, with the damage sustained during the revolution not being repaired until 1845.
- The Notre-Dame was single-handedly recreated for Assassin's Creed: Unity by Senior Level Artist Caroline Miousse, who spent more than two years on constructing the iconic monument. While most of the cathedral is faithful to the original, creative liberties had to be taken with most of the art that adorns it, which is protected under copyright law.
- On April 15 2019, at 6:30 p.m. (local time), Notre-Dame caught fire. According to French authorities, the cathedral barely escaped complete destruction, having been only 15 to 30 minutes away from structural damage so severe it would likely have caused the building's collapse. In order to help, Ubisoft pledged €500,000 to help Notre-Dame's reconstruction, and made the PC version of Assassin's Creed: Unity free to download between April 17 and April 25 with messages encouraging donations to help restore Notre-Dame. Additionally, IGN noted that Unity could be useful in helping rebuild Notre-Dame due to how accurate its map of the cathedral is.
