Our rehearsal room is in one of those bunkers. They are sometimes ridiculously complex with all the corridors and rooms, but they are indeed extremely sound.
Comment on Anon is unimpressed

There are a bunch of Flak towers from WW2 all over Europe that were so massive and structurally sound that it was pretty much impossible to tear them down after the war. The Soviets tried to blow up one in Berlin and it literally just split in two. It was deemed too much work to dismantle it so they just piled rubble on top and turned into a hill.
There’s another larger one in the center of Hamburg and the Brits calculated that the amount of explosives needed to bring it down would level the entire city, so they left it. Another one in Hamburg failed to blow up with 16 tons of explosives. Only the interior walls collapsed and the exterior remained intact. It’s still in use today.
I’d wager that these buildings could very well survive our current civilisation.

Why take them down at all and not repurpose them?

It probably had something to do with the demilitarization of Germany. But yeah, most of them were repurposed in the end. One is now a hotel, school and club, one is a green energy storage and another was turned into a massive aquarium.

Lol, for the most part ferroconcrete with steel reinforcements. But the main reason they are so indestructible is just the fact that their walls are between 2 and 4 meters thick. They were designed to shrug off direct hits from 1000kg bombs.
