With its iconic 32m high dome and circular auditorium, the Colosseum in the Norwegian capital Oslo was the biggest and most modern cinema in Scandinavia when it opened in 1928. Over the intervening 90 years it has remained extremely popular, with audiences enjoying the biggest screen in northern Europe. It has maintained a long history of staying up-to-date with the latest cinema technology, which is why it has relied on Alcons pro-ribbon audio systems for the past 10 years.
