Since 2014, one weekend a year, Koll an Aktioun offers a wide-ranging program for families as well as  , culture-, cuisine- and and music lovers alike. Over the years, the festival, set in the stunning and historical Musée de l’Ardoise in Haut-Martelange, has become an integral part of Luxembourg’s event calendar with over 3.000 people attending each year. Koll an Aktioun is organised by more than 100 volunteers who not only share their passion for music but also for the environment. Minimizing its impact on nature is one of the essential components of the Koll an Aktioun. Sustainability is key!
