Pálení Čarodějnic: Witch Burning Day

I don't know exactly why, but I've pretty much been looking forward to Pálení Čarodějnic since I got to Prague. I have this handy guide book that tells me all the major holidays and festivals in Prague and the nearby areas and the moment I read about a day celebrated with bonfires and beer, I was in without question. 

This lady is going to burn later.
