Since 2014, for one weekend a year, Koll an Aktioun has been offering a wide-ranging programme for families, as well as lovers of culture, good food and music. Over the years, the festival, set in the stunning historical Musée de l’Ardoise in Haut-Martelange, has become an integral part of Luxembourg’s cultural calendar, with over 3,000 people attending each year. The Koll an Aktioun is organised by more than 100 volunteers who not only share a passion for music, but also for the environment. Minimising our impact on nature is one of the foundations of the Koll an Aktioun. Sustainability is key!
