      Depends. 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 it 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 thousands of years.

          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.

          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.

        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.

      Plenty of things build today will last much longer:

      Every nuclear waste disposal site (hopefully)

      Seed vaults

      Nuclear bunkers

      If you look into pyramid building theories, you’ll see that is rather difficult to lift such heavy stones at such heights at such a speed. It’s likely they even used river-based hydraulic force. I’d say quite advanced compared to what else we see from 4k years ago. There’s many great resources and this topic (and many bogus ones), but for simplicity, I’ll link to Wikipedia here.

        They virtually build themselves. Though whipping in the summer heat can be laborious.

    Pretty sure they have some cool castles in denmark. They did at one point at least, around the early 1600’s I know they had castles with batteries around their straits to enforce tolls for ships passing through, the monarchies main source of income.

    I mean… I don’t find my country super impressive either, but Tolkien based middle earth on Djursland and both Aragorn and Eowyn are based on the same character from an old Danish myth about Hervør, the shield maiden who dressed like a man to gather an army. Isengard, Helms Deep and Esgaroth are real places in the area.

    Hamlet is also based on the myth about Amleth and his grave can be visited in Denmark if people can be fucked to find it.

    In fact, we have so many viking graves all over the countryside, that tourists don’t even realize what they are until they are told. My Ukrainian friend was thrilled to get to stand on one and he started talking about the riders of Rohan and their graves and all that. He was almost about to keel over when we told him we weren’t that far away from the part of Denmark that Tolkien based Middle Earth on.

    Ps: I haven’t seen the pyramids irl, but I think they are amazing. Still insane how they were created without modern technology. I can’t hate on them even if I wanted to.

    Problem with the pyramids is that there are so many of them that it starts to just seem like a normal thing to do. And in various parts of the world.

    I wonder if the Mayan ones surrounded by forest had to lop down lots of trees to make way for the moving stones, or if the forest came later.

    Danmark actually has pre historic construction. But, you could very much see dolmens as stacked rocks, more than the pyramids.
