In 1928, in Oklahoma, a stone wall made of the strongest blocks was found in a mine at a depth of 420m, about which tools simply broke
Archaeologists and experts have established that the height of the wall is exactly 18m, up to a millimeter, and the width is 54m, also up to a millimeter.
The blocks are perfectly square, and you can't even insert a knife blade into the gaps. According to the depth of occurrence, the age of the formation should be estimated at 240-250 million years.
In 1983, an explosion occurred at the mine, and it collapsed. Despite the interest of geologists and archaeologists, the dungeon was preserved and the inconvenient question of who and when built the wall at such a depth remained unanswered.
