The effort to rebuild Notre-Dame Cathedral could get help from an unlikely source: A video game

A fire on Monday devastated the iconic Notre-Dame Cathedral in Paris. The structure, including its two main towers, remains intact, but its spire collapsed before firefighters could contain the blaze, Business Insider reports.

French President Emmanuel Macron has vowed to rebuild the famous cathedral, tweeting in French: "We will rebuild it. All together."

One potential source of help in those efforts is the 2014 video game "Assassin's Creed Unity," which is set in Paris.

As detailed in a 2014 feature published in The Verge, Caroline Miousse, a Ubisoft level artist, spent two years poring over details of the cathedral to create as accurate a depiction as possible in the game.

"I made some other stuff in the game, but 80% of my time was spent on the Notre-Dame," she said at the time.

That's because the cathedral is a centerpiece in "Unity" that players can explore inside and out. The "Assassin's Creed" series is known for its lovingly detailed re-creations of historic places, and the Notre-Dame Cathedral in "Unity" is no exception.
