Traboules (Hidden Passageways)

These secret passageways threading through Lyon's Renaissance and Baroque neighborhoods offer a glimpse into centuries-old urban life, where residents once moved between buildings unseen. Originally designed during the 16th-17th centuries for silk weavers to transport delicate fabrics and later used during religious conflicts, the traboules represent an ingenious response to Lyon's densely packed hillside neighborhoods. Walking through their shadowy corridors feels like stepping into a hidden layer of the city that tourists rarely discover.
