Hexenbrennen

Machine-translated from the German article

Hexenbrennen (also Hexenfeuer; Upper Sorbian Chodojtypalenje) is a Sorbian fire custom widespread mainly in Upper Lusatia and the Sorbian settlement area there, in which a tall, widely visible bonfire is lit on Walpurgis Night on 1 May. Young people build the "witch pile" of dry wood at a suitable spot, usually on a hill, and guard it against premature burning by the youth from neighbouring villages.
