Light Guerrilla FestivalSvetlobna gverila

Svetlobna gverila is an annual international festival of light art in Ljubljana during late spring. It features light installations, projections, and multimedia artworks scattered throughout the city. In 2025 (its 19th edition), the festival's theme is 'Disruptions', exploring how light as an artistic medium affects perception and everyday life 1 2. The three-week event includes an exhibition at Galerija Vžigalica and nightly outdoor light showcases on streets like Špica and Metelkova. Visitors experience a city transformed by creative lighting and interactive exhibits.

Launched in the mid-2000s by Ljubljana’s cultural community, Svetlobna gverila highlights contemporary art and urban space. Over the years it has become a fixture in Ljubljana’s cultural calendar, linking modern art with public space. Each edition has a conceptual theme; 2025's 'Motnje' (Disruptions) shows artists engaging with social and urban 'disturbances' through illuminating installations 1 2.
