The idea behind the Oslo Opera House came after a role switch. When first opened eight years ago, visitors were presented with a fairy tale, allowing everybody to literally walk on top of the glacier-like surface of the building before being lured inside, into an adventurous quest for the “Hall of the Mountain King” (According to Norwegian folklore, The Mountain King normaly resides inside the Dovrefjell mountain range, who’s highest peak – Snøhetta – incidentally has the same name as the architect company that drew the Opera House). It was an iconic building that soon became a part of the identity of Oslo, and the web site still melts down twice a year, when next season’s tickets are out.

It’s a glacier. You’re supposed to walk on top of it
So how did they come up with this idea?
