Unreasonable stairs around the world where you can't help but wonder, 'Why is this happening?'

From time to time, people wonder, 'Why did you make something like this ... Why didn't anyone say something was wrong while making it? Why didn't anyone stop it? Why? Why?' There are many things, but among them, weird stairs are scattered all over the world, probably because it is easy to make a mistake about 'stairs'.

So, various images of such strange stairs are from the following.
Builders + Beer + Insane Architects = Stair Fail

It looks like a deception picture, how do you get up?

Pillar in the middle of the stairs, too disturbing

Stairs like a cliff

Escalator that can hit your head

unreasonableness

In the wall

Where are you coming from and where are you going ...

Trees are growing ...

Failure

Cross the window

And a monument that symbolizes those stairs. I feel a strong will that no one should nantoka and cause the tragedy of the stairs anymore.
