They Stumbled Across This In The Woods... Beneath It Was A Terrifyingly Awesome Secret.

Deep in the woods in the middle of northern Germany there are strange, periscope-like pipes that are jutting out of the ground. One day, a group of friends stumbled across them in the former German Democratic Republic territory. They decided to explore the area, even though it seemed a little dangerous. What they found hidden beneath the ground was historically interesting ... but also terrifying.

The Friends used to play there as kids but never explored what was  connected to the pipes.

But it was time. The entrance was originally covered with a wooden lid, but it was removed with a crowbar.

The view from inside the entrance,  iron door and all

There were endless, hospital-like hallways....

Acoustics inside of the bunker make everything  more horrifying.
