We were in France and Germany. Ach! Włodek made photos, it is why we are only two of us on all those pics:

Do you have any idea, where we are / what it is on that last photo? If you find out, let us know and you get a price :-). You do not have to know the name of the place only that “thing”.

The riddle is immediately solved by Sigrid – we are in a maze! Isn’tit amazing?
