Rijeka Summer Nights 2026 transform the city into a vibrant open-air stage, presenting an extensive programme of theatre, music, performance and urban arts across iconic locations – from the Croatian National Theatre Ivan pl. Zajc and the Delta area to Trsat and Rijeka’s former industrial spaces. This year’s highlights include premieres such as Čvor, To=To and Kazalište, alongside spectacular concerts by the Rijeka Symphony Orchestra (Serenada ljetne noći, Opera in Flames) and performances by acts including Psihomodo Pop, Dolce Garbo Ensemble and Opera Rockstar. With circus and acrobatic shows, workshops and site-specific productions, the festival confirms Rijeka as one of the Adriatic’s most dynamic summer cultural stages.
