Oslo - shoppingcenter architeture

I think that Oslo probably is one of the architectually ugliest cities in the world. Well, the money was pouring in from the oil - and it seemed like they just built without ever thinking about the overall plan. Its like a face that has many nice details, they are just not well porportioned or put together. However, the details were nice, and one of them is this shoppingcenter roof in the center of Oslo.
