RockOpera Praha is the only Czech theatre dedicated exclusively to original rock operas, growing out of the cult band King Size when composer Milan Steigerwald and librettist Pavla Forest transformed it into a full theatrical company in 2006. Their semicircular arena in Prague's Holešovice district seats 777 and brings together rock stars such as Kamil Střihavka and Eva Urbanová alongside acrobats, fire performers and a live band on stage. The repertoire spans ancient Greek tragedy, Goethe, Tolstoy and Norse mythology - all adapted solely by Steigerwald and Forest.
In April 2025, the theatrical premiere of the new rock opera King Size: RockOpera took place, which tells the true story of the theater's founders and the behind-the-scenes of Czech show business.
RockOpera Praha performed in April 2025 in the Ostrava Gong hall with two performances - Ragnarock: Vikings and The Little Prince.
In January 2026, the premiere of a music video for the song Be Better from the opera Ragnarock took place on the RockOpera YouTube channel, featuring Kamil Střihavka, Pavla Forest and others.
The new season 2025/2026 was officially opened on September 18 with a revival of the opera Troy; the theater prepared a total of 15 performances, including a New Year's novelty.
Another performance of the ensemble in the Ostrava Gong hall is planned for spring 2026.
