The ballet and opera performances of the Finnish National Opera enjoy international fame. Operas are sung in their original languages. The original Finnish National Opera was built in the 1870s as a Russian garrison theater, but in 1993 the opera house moved to its new home. The ticket office is open Monday to Friday 9am to 6pm and Saturday 3 to 6pm. On performance nights, the ticket office stays open until the performance begins. The opera and ballet season runs from September to June.
