Uncover the mysteries of "Le Secret du Roi," Louis XV's espionage plot.
📱 1 to 10 phones · 1 team per phone · Independent codes
Behind Versailles' splendor, a king weaves a web of secret influence.
Infiltrate the secret espionage network of Louis XV, woven through the golden salons and dark corridors of Versailles castle between 1745 and 1774.
Step into the shoes of Marc-Pierre d'Argenson, lieutenant general of police of Versailles, tasked by Louis XV with dismantling a plot against the crown in 1757. Starting from the monumental Place d'Armes measuring 340 meters, theater of court arrivals, embark on a ~135-minute investigation across 1.5 km from royal apartments to the secret gardens of Petit Trianon. At each step, open your phone: coded messages appear on Louis XIV's equestrian statue, luminous clues reveal themselves in the Hall of Mirrors, Baron de Breteuil's ghost whispers secrets in Saint-Louis Cathedral. Follow the traces of Joseph Fagon, the king's first physician, and uncover the mysteries of secret diplomacy played out between Latona's groves and Grand Trianon's salons. More than an outdoor escape game: an interactive visit immersed in 30 years of royal espionage, with anecdotes revealed at each stop and confidential sites that classic guides forget.

The story that haunts this land
Versailles in 1757 crawls with spies and conspiracies. The Place d'Armes, created in 1682 by Louis XIV spanning 340 meters, becomes your strategic starting point. At its center stands the equestrian statue of the Sun King, cast in 1683 by Girardon and Regnaudin, a rallying point for royal ceremonies where secret agents slip through. Marc-Pierre d'Argenson monitors suspicious arrivals, scrutinizing each carriage crossing this monumental esplanade. Beneath your feet, the cobblestones guard secrets of messages exchanged between court spies and foreign emissaries.
The Avenue de Paris, traced in 1682 over 3.5 kilometers and 40 meters wide, guides you toward the conspiracy's heart. This processional avenue, lined with 17th-century private mansions, served royal processions but also clandestine meetings. Louis-Charles Le Tonnelier de Breteuil, Secretary of State to the King's Household, organized his informant networks here between 1758 and 1783. Each facade hides an espionage story: here a salon of Madame de Pompadour, there an Austrian diplomat's residence suspected of intelligence with the enemy.
The Latona Basin and Marble Court reveal the secret codes of Versailles diplomacy. In the gardens created by Le Nôtre, Joseph Fagon, Louis XV's first physician and director of the King's Garden, transmitted medical information about royal health to European chancelleries. The Hall of Mirrors, 73 meters long and adorned with 357 mirrors, becomes the theater of secret negotiations where each reflection hides a spy. The royal apartments buzz with diplomatic whispers between masked ambassadors and double agents.
The Grand Trianon and Petit Trianon, built respectively in 1687 and 1768, shelter your investigation's final secrets. These intimate residences of Louis XV serve as refuges for the most delicate negotiations with European powers. Marie-Antoinette, future dauphine, would learn the art of secret diplomacy there from her mother Marie-Theresa of Austria. In these miniature castles' groves, treaties are signed in the shade of hornbeam hedges, far from the official court's prying eyes.
Your mission concludes at Saint-Louis Cathedral, built between 1743 and 1754 by J.-A. Gabriel, where the best-kept state secrets rest. This 72-meter parish church, consecrated in 1754, becomes the confessional of repentant conspirators. You carry away the key to Louis XV's espionage network: a diplomatic web woven between Versailles and European courts, where each castle stone hides an intrigue, each garden a state secret, each salon a negotiation that shaped 18th-century Europe.
