I saw a wonderful thread on Bonobo's Polish Culture Forum about the Christmas Szopkas contests in Kraków. Se the link below for more wonderful images of Szopkas.

Kraków szopka (pron.: shop-ka), or nativity scene (crib, crèche) (Polish: Szopka krakowska) is a Christmas tradition originating from Kraków, Poland, and dating back to the 19th century. An unusual and characteristic feature of the szopka is the use of historical buildings of Kraków as backdrop for the Nativity of Jesus.
