Вальбурга
Saint Walpurga or Walburga (, , ; c. AD 71025 February 777 or 779), also spelled Valderburg or Guibor, was an Anglo-Saxon missionary to the Frankish Empire. She was canonized on 1 May c. 870 by Pope Adrian II. Saint Walpurgis Night (or "Sankt Walpurgisnacht") is the name for the eve of her feast day in the Medieval period, which coincided with May Day; her feast is no longer celebrated on that day, but the name is still used for May Eve.
