What was once used as the main stage for Norwegian National Opera is now the Folketeateret, a privately-owned theater and music venue in the heart of the city. The remarkable architectural expression of the building remains intact with traditional elements blending seamlessly with modern techniques to create a memorable theater-going experience. Previous notable performances include Mamma Mia!, Buddy Holly and We Will Rock You. Seating capacity is 1,400. Check out the website for current and upcoming shows.
