Have a royal night out at the opera at the Pomeranian Dukes Castle, also called the Ducal Castle. This is where the residents of Szczecin come for their music and cultural fix. Admire the swirling white Mannerist architectural style of the castle from the outside, then step inside the city's cultural center which houses both cultural and administrative institutions, as well as the city's opera. The Pomeranian Dukes Castle Opera is Poland's only opera house which can say it has all the operas of Stanisław Moniuszko in its repertoire. Enjoy chamber music and classical concerts from international artists, as well as promenades on summer evenings, plus ballet and theater performances. The castle courtyard hosts an annual tournament of Great Tenors.
