EDIT: The game is also available in kids and teenager versions. 
For an escape game inside the Sacré-Coeur (Sacre-Heart), or around Notre-Dame Cathedral, go to Le Libre promeneur page.

We invite you to (re) discover the magnificent Montmartre district in a unique way.
This experience is an alternative to guided tours; it is a fun experience as well as a cultural one!
This escape game is also an opportunity for you to have beautiful photos of you and your loved ones taken, if you want to (free of charge), as your host is also a photographer. And you might even win a surprise gift…
You will have two hours to crack a code. Enjoy the unique atmosphere of the district, feel yourself almost part of the 2002 movie “Le Fabuleux Destin d’Amélie Poulain” (“Amélie from Montmartre” in English). And leave the area with the gift and the wealth of knowledge you will have acquired during these two hours - about the identity of Montmartre, its history, its artistic
tradition, its personalities, etc.)
You will crack the code by solving riddles focusing on the very best of the area: some
emblematic spots such as le Sacré-Coeur, la Place du Tertre, la Maison Rose, the vineyard, etc., but also other places, much less known and yet just as interesting. But we prefer to keep them secret here…

A bientôt ☺
