On Whit Monday each year, Wiltz hosts the traditional 'Gënzefest' - or 'Geenzefest' as people in the north of the Grand Duchy call it - to celebrate flowering broom.
Celebrated since 1949 in the Ardennes town, the Gënzefest honours the genista, a yellow-flowered shrub particularly abundant on the hills of the Oesling region at this time of the year, which literally bathes the landscape in a golden yellow every year.
The 'Geenzefest' is organised by the association 'Les Amis de la féerie du genêt de Wiltz' (the friends of the Broom Festival of Wiltz); it is best known for its impressive flowering broom parade: more than forty floats, all decorated with broom, together with music and folk groups from the Grand Duchy and further afield, parade through the streets of the town on Whit Monday.
As well as the parade, there is an extensive programme of festivities throughout the Whit weekend: exhibitions, the crowning of the Broom Queen, a flea market at the castle and in the main street, folk displays, concerts, shows, and a dance. Exceptionally, shops and museums in Wiltz are all open on Whit Monday.
Over the years, the 'Geenzefest' has become one of the most important folk events in the Grand Duchy, attracting nearly 10,000 visitors each year to the winding streets of the main town in the Ardennes area.
