Like other games in the series, "Unity" portrays a large number of real world Parisian landmarks, including the Tuileries Palace and Notre-Dame Cathedral and, through the time anomalies feature, it also includes the Eiffel Tower and the Statue of Liberty, neither of which existed at the time of the French Revolution. Notre-Dame Cathedral was modeled down to the brick, a process that took Ubisoft artist Caroline Miousse two years to complete. Because of the detail that went into the recreation of the Notre-Dame Cathedral for the game, some believe the game may help in the reconstruction of the Cathedral following the April 2019 fire that destroyed some of the building. Ubisoft donated €500,000 to the reconstruction of the cathedral and also provided "Unity" as a free download for the week following the event so as to give everyone a chance to explore the cathedral as they had modeled it in game.
