Watch FMovies. Eugen Suchoň's opera Svätopluk returns to the stage of the Slovak National Theatre Opera in 2023. Since 1960, when it had its world premiere, this is the fifth production of this musical drama at the Slovak National Theatre. It returns as an eloquent witness of Slovak operatic history, as a bearer of a message, as an impulse for reflection and reassessment of historical attitudes in a broader context.
