Nonagon Festival 2026

Audiovisual art and experimental music festival in the oil cisterns of Svanö island, Ådalen. On 16-18 July 2026, the fifth edition of Nonagon Festival will be held at the abandoned oil cisterns on Svanö island in Ådalen. The two massive, cylindrical spaces, with a reverberation of up to 25 seconds, become a living instrument for artists to explore. The programme consists of musicians, visual artists, performance artists exploring genre-defying practices and techniques, as well as workshops open to all ticket holders. On 16 July, Lamour Records will host the festival opening by the sauna next to the river. The opening night is free and open to everyone. The festival grounds are open 17-18 July between 10:00-02:00.

Our mission is to craft unforgettable art and music experiences for both visitors and creators, where the lines between art forms are blurred and blended.

NONAGON's goal is to be a driving force for experimental and innovative audiovisual art. We invite musicians, visual artists, sound and performance artists to come together and create in these one-of-a-kind spaces – where art takes unexpected and boundless forms.
