Central Europe's largest music festival, held every July in the spectacular industrial setting of Dolní Vítkovice — a UNESCO-listed former iron and steel works in Ostrava. Over four days, 150+ acts perform across multiple stages, blending rock, pop, electronic, jazz, and world music. Past headliners include Radiohead, The Chemical Brothers, Massive Attack, and Portishead. The converted blast furnace backdrop makes this one of Europe's most visually striking festival venues.
