Walpurgis Night

Walpurgis Night is a Christian feast day celebrated on the night of April 30 and the day of May 1, commemorating the canonization of Saint Walpurga, an 8th-century abbess in Francia, and the movement of her relics to Eichstätt. The feast day is associated with the legend of Saint Walpurga, who was said to have battled pest, rabies, and witchcraft, and is still celebrated with bonfires and pilgrimages to her tomb in Eichstätt. The holiday is observed in various forms throughout Northern and Central Europe, often under local names such as Valborgsmässoafton or Vappu, and is linked to older May Day festivals and traditions.learn more on wikipedia
