Charles de Batz de Castelmore, known as d'Artagnan, rose from a poor Gascon nobleman to captain of King Louis XIV's musketeers—a man who knew too many secrets
You are a Royal Cipher Agent, secretly dispatched by the Sun King to Auch, Gers, in 1673.
Your objective: decipher the last coded messages of Charles de Batz de
Immerse yourself in Auch, a Gascon city where d'Artagnan's shadow still lingers, to thwart a final conspiracy that could change the fate of Nouvelle-Aquitaine.
Your quest begins at the D'Artagnan Monument, in Place Salinis, Auch. This imposing statue, erected in 1931 by sculptor Firmin Michelet, immediately confronts you with the mythical figure of the musketeers' captain-lieutenant. It is here, facing this representation of the Gascon hero, that the first clues are revealed. The scavenger hunt invites you to scrutinize the details of the work, searching for hidden symbols related to his last mission. This family-friendly introduction to Auch immerses you in the world of this emblematic character, whose real history is intimately linked to Nouvelle-Aquitaine.
The investigation then leads you to the Monumental Staircase, a structure of 370 steps built between 1860 and 1863, connecting the upper town to the lower town of Auch. Although post-dating d'Artagnan's era, this edifice is a historical convergence point for inhabitants and travelers. From its summit, the panoramic view of the Gers valley offers a strategic perspective, essential for a secret agent. Here, you decipher a message that directs you to the city's religious heart, a key element for understanding the influence networks of the time.
Auch Cathedral, a masterpiece of flamboyant Gothic and Renaissance art, is your next stop. Its construction spanned over two centuries, from 1489 to 1680, thus encompassing d'Artagnan's lifetime. Its 16th-century stained glass windows, works by Arnaud de Moles, and its carved choir stalls, provide a sumptuous setting for a new enigma. The solemn atmosphere of this historic monument in Nouvelle-Aquitaine contrasts with the urgency of your mission, but every architectural detail can hold a vital clue for the rest of the thematic circuit.
Your journey guides you to the Armagnac Tower, a 14th-century former keep that served as a prison. This medieval vestige, emblematic of Auch's heritage, stands as a silent witness to past intrigues. D'Artagnan himself, as a figure of royal authority, could have imprisoned conspirators here. The treasure hunt invites you to explore the surroundings of this tower, searching for marks left by a prisoner or a message hidden in its old stones. It is a place conducive to discovering the buried secrets of Auch's history.
Finally, your itinerary leads you to the Saint-Pierre Bridge, spanning the Gers. This bridge, which has witnessed centuries of trade and travelers, is the final point of your exploration. It is here that d'Artagnan's last message is revealed, a final warning against a forgotten threat. This interactive visit to Auch will have allowed you to retrace the steps of a hero, decipher enigmas, and discover the rich heritage of Nouvelle-Aquitaine. This outdoor escape game leaves you with the certainty of having uncovered a secret, enriched by an immersive stroll through the heart of Gascony's history.
