In southern Germany the hexagram is the symbol for the
tapping of beer and sign of the brewer's guild. In German this is called
'Bierstern' (beer star) or 'Brauerstern' (brewer's star). This room in [King
Ludwig II's "Fairy Tale Castle" of Neuschwanstein ] the gatehaus was where the
castle staff would go to eat, away from the Palace, but still within the castle
walls.
