Behind this unique concept is Guillaume Besançon, a former public works engineer who has directed projects such as the Musée du Quai Branly. A games author and founder of Salon Fantastique and Jeu de Rôle Magazine, he has imagined a place where "the spectator-players are the heroes of the story".
As he sums it up: "This is the first time in the world that a life-size dungeon has been built. A geek's dream come true, accessible to all."
On site, six professional actors bring this moving theater to life. Every session is different: costumes, dialogue and combat adapt to players' decisions.
Whether you're a diplomat, mage or thief, your choices change the course of history in real time. Put on your costume, grab your foam weapon, and set off on a 600 m² adventure, filled with suspension bridges, secret passages and twisted puzzles.

L'Aventure Fantastique also stands out for its commitment to the environment: housed in an old, forgotten theater, the venue has been refurbished without producing waste, and benefits from a naturally regulated temperature.
The experience extends beyond the game: your earned gold coins can be used to purchase new spells or equipment via a dedicated app.
And if you're feeling daring, try out Thursday's hardcore mode, with more powerful monsters and more intense scenes. Starting in September, a new scenario will also be offered on Monday and Tuesday evenings!
