In case somebody thinks, that I do not appreciate the beauty of Cracow (center of the city), here are some photographs taken in 2007 or so.
There are those beautiful doors in Cracow.
The ones featured here are but a few examples.
To me, it seems to be a kind of variation on a common style, a cultural matrix.
But I do not know enough about the culture (I guess, it has not been done without some Jews involved).
