This is from inside the "round tower" in Copenhagen, Denmark.
It has no stairs, instead there is a spiralling corridor all the way to the top!
Czar Peter the great rode up there on horseback when he was visiting Copenhagen in 1902!
Here is also an earlier upload - from the outside:

Later comment:
Hmm, I havenīt gotten all that much response to this picture (although it is one that Iīm fairly satisfied with).
But I guess that it is rather sterile to look at.
-Try to look at the road as sort of "flowing" down, it gives some movement to the image :-)
