June 18th, Boxmeer. The "Boxmeerse Vaart" is an ancient Holy Blood procession that originated in the year 1400 in Boxmeer. Thousands of people attended the Procession, which has been held every year on second Sunday after Whit sun. The tradition recovers that a priest doubted to the conversion of bread and wine into the body and blood of Christ. Blood sparkled over the cup and a drop of blood remained on the corporeal (white linen) behind after the priest its error recognized. This white linen has been kept in the old silver reliquary remained and put away and becomes shown in the Boxmeer-Procession.
