Held annually over 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 karaoke bar, and much more. The public village — a space that is free and open to all — features 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.
