The Chaumont branch of the Agence d'Attractivité de la Haute-Marne is offering a brand new fun and immersive experience: Le Secret du Cerf d'Argent, a brand new urban treasure hunt for the general public. Available from Monday 25 May 2026, this trail invites participants to (re)discover the historic centre of Chaumont through a captivating investigation combining riddles and legend.
It all begins with a mysterious manuscript found by an explorer.
It tells of a stag with a silver antler, the town's legendary protector, whose identity has been lost. Your mission? Solve the riddles scattered around the town, piece together a secret code and unravel the mystery before it disappears forever.
Each team will start the adventure at the Chaumont branch of our Haute-Marne Attractiveness Agency, equipped with a tote bag containing all the materials needed for the investigation. Observation, reflection and team spirit will be essential to successfully complete this mission.
This project has been entirely designed by the Agence d'Attractivité de la Haute-Marne, with the aim of promoting local heritage in an original and fun way.
