It is a majestic structure nestled among the mountains just meters from the border with France. At the time of its inauguration in 1928, the station was the second largest in Europe.

The vastness of the building is matched by the numerous stories and mysteries held within its walls. During World War II, this station witnessed the passage of tons of looted gold from Europe, tungsten destined for Nazi war machinery, as well as Jewish refugees, Allied spies, and members of the Gestapo.
