What is the Easter Fire in Germany, and why is it lit? The Easter Fire, or Osterfeuer, is a symbol of light in the darkness. It can be as simple as lighting a candle, or as big as the bonfires which are ignited all over in Germany at Easter. Because fire is a symbol of light, of renewal, it signifies the end of Winter, and the coming of spring. It also symbolizes Jesus Christ, as the Light of the world. Depending on the community, the Easter fire is lit on Good Friday or Black (Holy) Saturday, with Saturday being more common, and extinguished on Easter Sunday or Monday.
