Oslo, Norway - an opera house and a ski-jump

Norway, with a population of 5.2 million, is about the size of Montana which is home to just over 1 million. Oslo, where about 660,000 live, is the capital city of Norway and it is situated at the head of the Oslofjorden. 
A great deal of construction was going on all around the city making for plenty of traffic jams. By and large, there is not much to see in Oslo and popular sites to show to tourists comprise a quirky opera house and the Olympic ski jump. Some more images here.
