The Colosseum Kino in Oslo, Norway is the largest cinema in Northern Europe[1] and the largest THX cinema in the world.
[2] It is distinguished by its large spherical dome.
Colosseum has hosted several premiere parties and long-running movies, notably My Fair Lady and The Sound of Music.
In the 1966-1967 period, more than a half-million people (more than the total population of Oslo at that time) saw The Sound of Music in the Colosseum.
