Easily recognisable, it's the witch's house from the Hansel and Gretel story, the model for all those booths at German frost markets and many Christmas decorations.
But, why? What have snow covered forest cabins got to do with Christmas? Where did the tradition originate? Googling did not help this time. I know they came from Germany, but how did gingerbread houses become part of their Christmas traditions?
I have a feeling I am going to ask that question quite a lot as I think about the meaning and origins of many items on the Advent wreath
