ABOUT KOLL AN AKTIOUN
Koll an Aktioun is organised by Kollibri asbl at the historic site of Musée de l’Ardoise in Haut-Martelange. Since its first edition in 2014, the festival has attracted up to 3.000 visitors on Pentecost weekend.

THE FESTIVAL FOR EVERYONE
This multidisciplinary and participatory festival offers a diverse program featuring music, street art, a local market, an exhibition, workshops, and gastronomy. There is something for everyone to enjoy at Koll an Aktioun. All while upholding the principles of sustainability, gender equality, and the circular economy.
Since its inception, Koll an Aktioun has aimed to provide a regional program that is accessible to all. To put these values in practice, we have deliberately designed our pricing policy accordingly. acc
PAY AS YOU CAN
By adopting the "pay as you can" principle, combined with a minimum price, we enable those who are more financially able to help provide access to the festival for those with fewer resources.
Moreover, discounted entry through the Kulturpass is also available as an alternative. As a family-oriented festival, we offer free admission to children and young people under 16.
