April 1st, Ootmarsum. Ootmarsum is the only Dutch town to continue several Easter traditions. Also it's one of a few towns in Overijssel to have a festive Paasvuur (Easter fire). This tradition that dates back hundred of years to pre-Christian times and it's always celebrated on Easter Sunday. The Dutch traditionally lit Easter bonfires to ensure fertility (the ash going back into the ground) and to chase the winter demons away. During the Easter fire, the "Poaskearls" or the Easter-men were in charge of the fire.
