North Bohemian Theater of Opera and Ballet, Opera and ballet theater in Ústí nad Labem, Czech Republic

The North Bohemian Theater of Opera and Ballet occupies one side of Lidické náměstí in Ústí nad Labem, in a Neo-Baroque building with Art Nouveau elements that has been a cultural monument since its professionalization in 1909. The auditorium holds 800 people. A smaller annex behind the main building houses the technical facilities.

The building was designed by architect Alexander Graf and opened in 1909 with a performance based on a work by Franz Grillparzer. Since its completion, it has served as an important venue for performances and hosted many artists.

The theater plays an important role in the city's cultural life and regularly presents opera and ballet performances. The ensembles work with artists from different countries who bring varying styles to their productions.

The auditorium seats 800 people, the capacity the city set in 1906 when it commissioned the building. The main house forms one side of Lidické náměstí, with the city museum beside it and a technical annex behind. The opposite side of the square holds the listed magistracy building from the turn of the 1950s and 1960s.

The 1906 architectural competition drew 42 entries; the jury ranked Rudolf Kraus first, but his Neo-Baroque design would have cost over 1.4 million crowns. The city instead chose the cheaper proposal by Alexander Graf, who had not even reached the shortlist, and the final cost still exceeded one million crowns.
