In the small town of Ootmarsum, a tradition known as "vlöggeln" is practised annually around Easter. Firstly, a group of eight young bachelors called "Poaskearls" (Easter Men) are selected. On Easter morning, the "Poaskearls" form a human chain by joining hands. They go through some of the houses of the town while singing psalms, after which the other inhabitants and other spectators may join the chain. After a while, the chain halts in the town centre, where fathers may lift their young children three times, while shouting "Halleluja". The gathering continues towards the fields, where a large Easter Fire has been built by the community. The gathering sings a psalm and then the "Poaskearls" light the bonfire. It is commonly believed to be a Roman Catholic adaptation of a pre-Christian fertility tradition.
