Bunkr [Bunker]

At the end of the Second World War , a civilian shelter was built, which was supposed to be used to hide the warlords. The cover has not been used in the last decades, but should still be functional . (or rather it is still included in the list of functional civilian shelters). It is not currently used to shelter the civilian population, that is the subway, which is very close to this shelter. But what if it was necessary to use this cover quickly? Is it still functional? Even after all these years, can he protect a potential hideout , even if his equipment is essentially historical? How would people connect with the outside world, and how would they actually find that they could leave the shelter without being in immediate danger? Let's hope it never happens and no one has to experience it themselves…
