Nov 11th is Sankt Martinstag or St. Martin's day. On this day, the streets of Germany are filled with children in procession holding lanterns in their hand, usually behind "St. Martin" in his Roman's soldier uniform and riding a white horse. The cold wintry evening of November is resounded with the children's voices singing to "Ich geh' mit meiner Laterne" translated to "I'm walking with my lantern".
Houses along the path of the procession light the way with candles.
The procession then ends with a Martinsfeuer (bonfire).
