"Hugged by mountains and perched on a stunning coastline of fjords, Bergen, Norway's second-largest city, has picture-postcard views.
As one of the centres of Norway's booming oil and gas industries, it is also a very wealthy place.
Yet there are few displays of ostentatious spending - there are no supercars with tinted windows, no designer handbag shops, and no queues of people outside exclusive nightclubs.
For while other countries have struck oil and then binged on the revenues, by contrast Norway is continuing to invest its oil and gas money in a giant sovereign wealth fund."
