All in Action Festival

festival
Organised every year during the Pentecost weekend on the historic site of the Slate Museum in Haut-Martelange, Koll an Aktioun has forged in more than a decade a reputation as one of the most creative, community-oriented and value-driven festivals in Luxembourg.
This year's festival offers over 50 cultural events, including more than 20 concerts by local and international artists, as well as workshops, street performances, film screenings, karaoke, and much more. The public village, a free space open to all, hosts a craft market, a food area, and spontaneous creative activities throughout the weekend. Access to concerts and certain performances in specific areas will require a ticket, but the heart of the festival will remain open and accessible to everyone.
