NIJMEGEN, GELDERLAND, NETHERLANDS - 2022/07/17: People are seen dancing and raising their hands in the air during a concert. The Vierdaagsefeesten (in English the meaning would be something like The Four Days' party) is the largest freely accessible event in the Netherlands and the fourth largest event in Europe. The Vierdaagsefeesten is held simultaneously with the International Four Days Marches, the worlds biggest multi-day walking event. Every year this event presents a program that attracts people to make over 1.5 million visits to the inner city of Nijmegen, the oldest city in the Netherlands. The party starts the weekend before the four days walking, and lasts until the same Friday when walkers and party people say goodbye until the next year.
