Maypole
May 1st is celebrated as Workers' Solidarity Day worldwide. However, even before the emergence of trade and labor unions on April 30th, ancient Europe had the tradition of holding triple processions of mummers who, with the sound of pipes, bells, and rattles, chased away evil spirits on Walpurgis or Philippi Night. Additionally, some folks raised the trunk of a century-old tree as a symbol of fertility and the beginning of the warm period of the year. The custom of putting up a maypole is prevalent in various European countries such as the Czech Republic, Slovakia, Poland, Austria and Germany.
