The place
A lodge,
an escape game,
a living place.
An overnight escape game with lodging, yes — but more than that. One night, several experiences. You play, you sleep, you taste, you discover. Les Granges fits no single category.
As a lodge: six bedrooms for the night, on top of the eleven game rooms. Made beds, quiet sleep after the adventure. At the table: local drinks and hearty Cambrésis cooking, a shared dinner mid-evening, morning coffee. As a game: a seven-hour overnight escape game, designed by Chasseurs de Mystères.
And around it all, a heritage that quietly inhabits the place: Caudry lace, local breweries, Matisse country. A cultural retreat as much as a leisure escape.
Who it's for
An escape game,
for individuals and companies.
Individuals
Among your people
Private long-format overnight escape game sessions for groups of 6 to 12. The full night: dinner at dusk, seven hours of play, lodging and morning coffee. Birthdays, bachelor/ette nights, friend reunions, escapes worth taking.
Companies
For your team
A long-format escape game with twin-room lodging, tight-team team-building format, up to 14 people. Not a mass seminar — one real night together to bond a team, co-founders or partners. The whole estate, privatised for you.
The night
A long-format escape game: from dusk to breakfast.
Arrival
You reach the estate, you settle into one of the six bedrooms. First drink in hand, the threshold isn't crossed yet.
First thresholds
Two to three hours of play. The puzzle takes hold, you start to feel the estate.
At the table
A pause, mid-game. Local drinks and hearty Cambrésis cooking. You breathe, you debrief, you try to figure out — together — where the night is heading. Pure conviviality.
The full night
Back to play. Hour after hour, room after room, all the way to dawn.
Coffee
Breakfast under the glass roof. Time enough to come back to the world.
