Rousse State Opera, Opera house in Ruse, Bulgaria

The Rousse State Opera is an opera house in Ruse featuring an opera hall and a concert hall, each accommodating over 600 people for performances. The building houses professional facilities for producing and recording musical and theatrical works throughout the year.

The Rousse Opera Society was founded in 1919, not 1914, and gave its first premiere on 23 April 1919 with Ivan Ivanov and Ventseslav Kautski's "Kamen i Tzena". In 1949 the society was nationalised as a state opera theatre, and its first production was Verdi's "La traviata" on 27 November 1949 at the Dohodno Zdanie, conducted by Konstantin Iliev. It became an independent institution in 1952 after "Don Pasquale" at the national opera review in Sofia, with Georgi Chendov as first director.

The company's name recalls the Rousse Opera Society of 1919, whose first premiere was Ivan Ivanov and Ventseslav Kautski's "Kamen i Tzena" on 23 April 1919. Its repertoire has given Bulgarian premieres to works such as Rossini's La gazza ladra and Stravinsky's Oedipus Rex. The orchestra also hosts the March Music Days festival.

The company performs in two halls, each seating over 600: an Opera House and a Concert Hall with a recording studio. The orchestra also hosts the March Music Days and Winter Music Evenings festivals. The building is in central Ruse, and the theatre has its own scenery-production workshops.

In 1999, the opera house merged with the Rousse Philharmonic Orchestra to form a single institution combining both art forms. This fusion allows the venue to present operas and orchestral concerts as part of a coordinated seasonal program.
