How Traversées Reveal Secrets Deep Beneath the City’s Surface Beneath the bustling streets and towering skyscrapers of many historic cities lies a hidden world—one that few ever see but all can sense in the quiet vibrations beneath their feet. Known as traversées, these subterranean pathways, tunnels, and passageways weave an invisible network deep beneath the urban surface, exposing secrets of the past, engineering marvels, and untold stories buried under layers of history. ### What Are Traversées? Traversées—a French term evoking movement through and beneath ground—refers to the network of underground tunnels, added passages, and concealed pathways found beneath major cities. These routes, often built for practical purposes like utility access or wartime refuge, now reveal remarkable archaeological, architectural, and cultural insights. Far from mundane service corridors, traversées connect the past and present, offering a rare glimpse into how cities were built, defended, and transformed over centuries.
