City Escape Collection · Carcassonne · 1688
A puzzle trail through Bastide Saint-Louis — at your own pace, with no guide and no group.
It is 1688. Lucas is a cloth merchant in Bastide Saint-Louis. His neighbour, Séraphin Bosc, claims ownership of his family warehouse — and the proof that could settle everything is locked inside a chest secured by three padlocks.
The combination exists. His grandfather, Balthasar, hid it in nine places across the Bastide. But Balthasar was a seer — he saw the future — and he described places that did not yet exist in 1688.
Lucas can read the letter. He cannot see what it describes.
You can.
"In his letter, my grandfather describes a fountain in the middle of the square, with a god at the top. I see only a market. What do you see?"
— Lucas Maffre, cloth merchant, 1688
Balthasar's chest
At each stop, Lucas reads you an extract from Balthasar's letter. You observe, you count, you write down your digit. Léo — Lucas's ten-year-old son — is there to help younger players.
At the end, you put your nine digits together to form the combinations for the three padlocks. Three attempts. Not one more — Balthasar would not have wanted that.
And if you open the chest, Lucas will share his favourite addresses in the Bastide.
