A bunker in the heart of Europe's heart. Resting under the Royal Park of Brussels, built to protect the local intelligentsia from the Nazis, but then discovered and used by the Nazis themselves. Connected by tunnels with the Belgian parliament, hidden under a theater and a club for rich people, reinvented during the Cold War in order to withstand a possible nuclear attack.
Now it lies silent, almost forgotten, memory for those who have the chance to visit it, that there was a period - not very faraway - when we needed to hide underground.
