Steel sheet piling wall birch tree grass.
Steel sheet piling wall with a straight birch tree in front of the steel wall, the green grass and brown earth is also visible.
I found this at a most beautiful location that you can imagine, a big natural environment with flora and fauna. All of a sudden you hit this huge steel wall that has been planted in the middle of the landscape for no reason as it seems. This wall is so big and high that you have no idea what is behind it, you can only guess.
