What Awaits You at the Ducey Code
It’s time to channel your inner Sherlock Holmes. Your mission: solve the mysteries of the Ducey Code at the Château des Montgommery.
The Ducey Code offers three different investigations, ranging from the simplest to the most challenging, ensuring there’s something for everyone. Participating in the investigation allows visitors to have fun while discovering the history of the castle and its owners.
Ducey Code – Three Levels of Difficulty
The Ducey Code is a life-sized police investigation game (not an escape game!). The difference? There’s no time limit; you solve the investigation at your own pace. Instead of being locked in a room, you freely wander through the castle, guided by the riddles.
Game 1 – Henri II’s White Horse (for children):
You’re part of King Henri II’s royal guard, tasked with finding his horse named “Malheureux,” which disappeared the day before a grand tournament. Your mission relies on observation and deduction skills. Clues are scattered throughout the castle, and a list of suspects is provided to help you solve the case.
Game 2 – The Malcontents:
A restorer is wanted by the police for stealing and hiding paintings and a famous manuscript. Amused by the situation, the restorer challenges you to find the manuscript using clues hidden in every room of the castle.
Game 3 – The Distillery Murders:
Following an unsolved murder that occurred in the castle’s old distillery in 1923, the case has been reopened. However, the investigator assigned to the case was also murdered. Your goal is to determine who killed these two individuals using your smartphone.
(This is the most challenging level of the Ducey Code, recommended for those over 15 years old who are accustomed to smartphone games.)
You’ll also have the chance to discover the castle
Alongside the crime scene, you’ll discover local history, mixed with that of France. We’ll learn of the accidental death of King Henry II, at the hands of Gabriel de Montgommery, who died of his injuries on 10 July 1559 after a tournament held on 30 June 1559.
This murder mystery also allows detectives to discover the wonders of the castle. Like the Italian coffered ceiling painting, for example.
Solving the Ducey code takes a little time. On average, it takes about an hour. It’s much better if you work together. The guides at the tourist office, can help you if you get stuck! You can register online now!
