The 24th Colours of Ostrava runs from 21 to 24 July 2027, once again inside the disused Dolní Vítkovice ironworks, where blast furnaces and a gasometer frame the stages. On 29 September 2026 the festival named its first headliner: Robbie Williams opens the Wednesday, 21 July. It is his first festival appearance in the Czech Republic after several solo concerts in Prague, and he brings songs from his album “Britpop” alongside hits from three decades — 2027 also marks thirty years since his solo debut “Life Thru A Lens”. The rest of the bill has not been announced; four-day passes are already on sale.
