Paris is a city steeped in history, and the capital's underground spaces are filled with memories from bygone eras, notably the First and the Second World War. In the early 1930s, the Paris authorities decided to develop 40,000 underground shelters to protect residents if needed. Today, you can still find some of these unused bunkers in the city's underground network, under the Eiffel Tower, beneath Gare de l'Est, or at the City Hall.
As you head to catch your train at Gare de l'Est, imagine that under your feet lies a bunker. Once a train-control hub, it remains remarkably intact, tucked beneath tracks 3 and 4. Built in 1939, the shelter secured a secret line of communication with the other Parisian stations and could house about 70 people in wartime. It was rarely used by the French; the Germans, however, completed its construction in 1941. Today it sits on SNCF property, occasionally open to visitors during the Journées du Patrimoine.
Even more unusually, did you know the Eiffel Tower housed its very own bunker, just as Paris City Hall does with its own underground shelter? As for the latter, it’s a place that never welcomed anyone. Indeed, it was built in 1937 after World War I to preempt future disasters.
The basements of four-storey buildings could also be viewed as underground shelters, much like the metro, which served as a refuge for thousands of Parisians. A notable part of Parisian heritage, this history testifies to the darkest hours of our past.
