Filip Švácha no, no, its is a tradition in my country, it has several roots, but the main idea is that you burn the witch and with her, all the bad things and winter cold, so you and the nature can be new and fresh again.
Viola Kuniej very interesting tradition. in Poland we have something like this - on the first day of spring we drown Marzanna's puppet - symbol of death and winter
Filip Švácha yes, in some villages people do the same, but this witch burning tradition is more spread.
Viola Kuniej burning man? ☺
