We are a norwegian family that will spend a couple of days off in Berlin this week. The plan is some sightseeing, geocaching and of course the christmas markets! 
This event is (hopefully) at the entrance to one of the big Christmas markets, Gendarmenmarkt. It opens at 11:00 this day, so we plan to explore it after the event.
We hope some local geocachers want to say hello to us here, or maybe some other cachetourists are in the area?
