Throughout your 2-hour guided tour you will discover the dark side of the center of Paris. Choose between a shared or private experience, which will begin at the former main site of the bloody and popular public executions, which were both adored and appreciated by Parisians. You will see how cruelly they used to punish convicted criminals, as well as the occasional unfortunate innocent person too. Paris is a haunted city with plenty of ghosts and phantoms. One famous French poet became the ghost that today haunts a theater, another one was injured during a fire and has since never left the Opera House. You'll learn about the "evil queen" of France, and how another spirit haunted her all the way up until her final days. Demons and devilish beings are everywhere in Paris, with the Notre Dame Cathedral containing plenty of them on its exterior. On this facade, there are so many creepy and mysterious signs and symbols, which require a thorough investigation to properly appreciate it. You will learn how a gypsy cursed a house in the Latin Quarter, causing its owner to die. This was followed by more people mysteriously dying there. You'll hear the spine-chilling story about this most famous cursed Parisian place, before your chilling tour finishes at the meeting point with the story of a vampire.

Solve clues and unlock horror stories as you roam Paris' haunted streets. Each clue will lead you from one place to another, giving you precise directions so that you won't need a map, GPS, or guide. After you purchase the quest, you'll receive an access code which you can use in the app. The quest will take you between 1-2 hours to complete, but there's no time limit which will allow you to have fun playing at your own pace. Throughout the quest, you will try to solve the curious case of Mona Lisa of the Seine, finding clues and encountering other spirits of the city. For larger groups, one person can purchase access for the entire group by selecting the number of people in the group. All group members will be able to play the city game on their smartphone. Alternatively, each person can purchase their own ticket. You can play as a group and solve the clues together as you walk, or you can split into smaller groups/teams and compete against the others. Each person can also play on their own, separate from the group, and meet the group at the end.
