The festival for everyone. For its 10th edition, Koll an Aktioun returns with a bold anniversary edition that pushes boundaries, defies categorization, and continues its mission to be much more than a music festival. Held annually over the Pentecost weekend at the historic Slate Museum site in Haut-Martelange, Koll an Aktioun has spent over a decade growing a reputation as one of Luxembourg’s most creative, community-based, and value-driven festivals. This year’s festival promises over 50 cultural happenings, including more than 20 concerts by local and international artists, as well as workshops, street performances, film screenings, a roller disco, karaoke bar, and much more. A new addition for 2025 is the introduction of a public village — a space that is free and open to all — featuring a creators’ market, a food village, and spontaneous creative happenings throughout the weekend. Access to concerts and select performances in designated areas will require a ticket, but the core of the festival remains open and accessible.
