Flak tower. Used against allied aircraft in Europe. They had an air defense range of 14km and could put up 8,000 rounds in a minute!!!
Some of those were built so strongly the cost of demolishing them to out something else there is so high they might be around in 500 or 1000 years
I want one.
I want to live in one 🙂
I’m quite the WW2 buff, but I’ve never seen one of the before…
