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…
