Croatian National Theatre Ivan pl. Zajc

Both an architectural and cultural landmark, Rijeka’s Croatian National Theatre was designed by the same team of architects as its namesakes in Split and Zagreb: Austrian Ferdinand Fellner and his German partner Hermann Helmer. In fact, the pair created dozens of theatres across Europe, from Odessa to Zürich, this one opened in 1885. Though Croatian-language performances here may be of limited interest, there’s also ballet and opera on the agenda, and the interior is worth a look around – Gustav Klimt and brother Ernst helped paint the ceiling before its grand unveiling, a performance of Verdi’s Aida.
