This religious event takes place every year on Whit Tuesday in honour of St Willibrord. It is unique to Echternach and dates back hundreds of years. Thousands of pilgrims from the region participate and it attracts as many spectators. The pilgrims progress slowly through the town, bouncing and skipping from one foot to another to a polka like rhythm. There are about 45 groups, in rows of five, following bands playing an ancient tune. Their destination is the basilica.
