Hello and Welcome all...
New subject are 'Stairs' - I needed jut a half minute to search my archives for this shot, taken few years ago in norwegian forests called Bymarka near the Trondheim city.
I have no idea where and what was standing there, but the stairs remains in a very well condition. The tree on a side can be a clue - it is a spruce, with this size, it has around 80-120 years. Near the stairs are also ruined basements of two other buildings so it could be a farm or an old turists hut of some sort.
And a little closer view of the same steps and the tree on a side.
