Took this shot at 4:25 pm. The Opera House was designed by the Norwegian architectural firm Snøhetta, which also designed the new library in Alexandria, Egypt. When I saw the initial renderings back in the early 2000s, I was very skeptical. At the time I seem to remember thinking that it looked like a scaled-up foam-board model (current and former architecture and art students will know what I am referring to). The design turned out to have been genius, especially because people have access to the roof, and on sunny days on weekends, the Opera House is covered with visitors. For that very reason, my partner refers to it as “the rookery”. One slight problem: the designers insisted on Carrara marble, which in the summer sun is dazzlingly white. However, sulfur dioxide bubbles up from the fjord and reacts with the marble, yellowing it in places. They could have used white granite, but that wasn’t white enough for them. We’ll see.
