In Lyon, France, you don't just walk through the city—you glide through it. The traboules, a network of hidden passageways threading between courtyards and buildings, turn a simple stroll into a treasure hunt. They were the original shortcuts, allowing residents to dodge rain, carry goods or move discreetly through the medieval quarters. Today, they're less about practicality and more about discovery. These passages date back to the fourth century but became essential during the Renaissance, when silk traders used them to shuttle delicate fabrics safely from workshops to the river without braving the weather. Later, during World War II, Resistance fighters used the traboules as escape routes.

Most of Lyon's traboules are tucked away in the Vieux Lyon and Croix-Rousse districts. Push open what looks like an ordinary wooden door and you might step into a courtyard with spiral staircases, arched galleries and stone corridors that snake between buildings. Some passages are public, some private and all of them blur the line between indoors and outdoors. Walking a traboule is like flipping through the city's footnotes. You're right in the heart of a living neighbourhood yet moving through centuries of history.
