Birutė (opera)
Birutė is a two-act opera composed by Mikas Petrauskas based on the play by Gabrielius Landsbergis-Žemkalnis. It was first performed on 6 November 1906 in Vilnius and became the first Lithuanian national opera. The plot is based on the medieval legend about the love between Birutė and Grand Duke of Lithuania Kęstutis recorded in the Lithuanian Chronicles. The opera was written for the amateur Lithuanian performers and thus is mostly valued for its historical significance.
