> searched for ancient advanced civilizations germans literally destroyed a lot of places and stole artifacts.  i know at least one place in north russia (place where no one lived and it was impossible to access until 1930s) which was a huge mystery giant sized cave system. with entrance that looked like a gigant bunker door.  what germans did with it? they stole everything that can be moved and destroy rest by explosions.  in 80s-90s there was a ussr/russia x usa expeditions to it. i participated and it was shocking.  some american leaked photos, but now everything removed from internet and gmaps.  expect that, there was also (in 50km from it? i dont remember well) foundations of ancient huge cities. but for the last 2000 years no one lived in that place and there was no information about such cities. maybe even for 4000 years.  i didn't participated in research of them, now all information about them is also removed.  sorry everyone, i got old and too tired to make readable text.
