“Ever wondered about the silent stories whispered by Parisian streets?” We stand before the Allée du Maréchal Mortier a seemingly quiet lane. Yet its name echoes with the thunder of history. This unassuming alley in the 20th arrondissement holds a significant piece of Parisian history. It’s named after Édouard Mortier a marshal of France under Napoleon I. Mortier’s military prowess earned him the title of Duke of Treviso. His name graces this boulevard as part of a larger ring of boulevards. These boulevards the Boulevards des Maréchaux were built following the demolition of the Thiers wall in the 1920s. The wall once stood where the boulevard now does. The creation of these boulevards connected Paris more closely with its surrounding areas.
But the Allée du Maréchal Mortier isn’t just a street name. It’s a location. A location deeply intertwined with the French secret service. Number 141 on this boulevard houses the Caserne des Tourelles. This isn’t just any barracks. It’s the headquarters of the DGSE the French General Directorate for External Security. The DGSE is the French equivalent of the CIA. Since 1949 the Caserne des Tourelles has been its central hub. The DGSE handles espionage counter-terrorism and cyber defense. The Allée du Maréchal Mortier provides a subtle but critical link to a critical part of the French government’s activities.
Interestingly since 1996 another building nearby became a part of the DGSE headquarters. These two sites are now linked by a secret tunnel running beneath the Allée du Maréchal Mortier. This tunnel a symbol of the DGSE’s discreet operations adds a layer of intrigue to this quiet street. The Allée du Maréchal Mortier’s connection to the DGSE is further amplified by the French television series Le Bureau des Légendes. Many scenes from this popular show were filmed here. The series helped popularize the image of the DGSE in the collective imagination. It is now widely associated with the 20th arrondissement. This relatively unknown street is now a clandestine setting for both real and fictional espionage.
So as we stand here on the Allée du Maréchal Mortier we’re not just looking at a street. We’re looking at a living testament to military history French espionage and even popular culture. This seemingly ordinary alley plays a pivotal role in both the past and present of Paris. It quietly hums with stories waiting to be discovered.
