Every year, on the Tuesday after Pentecost, the small town of Echternach in Luxembourg hosts a unique procession known as the "hopping procession." This procession, which has been taking place for over 600 years, is a UNESCO Intangible Cultural Heritage of Humanity and a must-see for anyone visiting Luxembourg.

During the procession, thousands of people make their way through the streets of Echternach, hopping rhythmically to the beat of a procession band. The hopping is said to represent the movement of St. Willibrord, the patron saint of Luxembourg, who is believed to have walked backwards to his monastery in Echternach after performing a miracle.

The procession starts at the Basilica of St. Willibrord and proceeds through the town to the crypt of the abbey. The crypt is believed to be the final resting place of St. Willibrord, and many participants take the opportunity to pay their respects and leave offerings.

The hopping procession of Echternach is a unique expression of Luxembourgish culture and an important part of the country's heritage. It has managed to survive for over 600 years despite various challenges and is a testament to the resilience of Luxembourg's people and traditions.

A commemorative stamp celebrating the hopping procession of Echternach would not only be a wonderful addition to any stamp collection but also a great way to raise awareness of this fascinating cultural event.
